How do I pull variables from an object in a list?

Me and a group of classmates and are working on a Spy Hunter clone for a project. I am making the spawner that will drop in our enemies off screen. I am going about this by having each tile of our procedurally generated road contain a script that will contain that tile's borders for the road set. The script for that is as follows (Prepare for unapologetic overuse of comments and whitespace):

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class RoadLimits : MonoBehaviour {
 
     [Header("Used to get the unique limits for enemy spawning for each road chunk.")]
     [Tooltip("Uncheck if the road chunk is water")]
     public bool isLand = true;
     [Header("Enemy Spawn width limiters.")]
     [Tooltip("Set to the left-most edge of the top of a road chunk where you want an enemy to spawn.")]
     public float leftSpawnLimit;
     [Tooltip("Set to the right-most edge of the top of a road chunk where you want an enemy to spawn.")]
     public float rightSpawnLimit;
 
 
     //The enemy spawner game object
     private GameObject spawner;
     //Ths script on the above game object
     private AJB_EnemyGenerator enemyGen;
 
 
 
     //Initializes at the beginning
     void Start()
     {
         //Assign the spawner game object and...
         GameObject spawner = GameObject.Find("EnemyGenerator");
         //assign the script component
         enemyGen = spawner.GetComponent<AJB_EnemyGenerator>();
         
         //When I am created, add me to the list in the EnemyGenerator
         enemyGen.roadLimits.Add(this.gameObject.GetComponent<RoadLimits>());
         
     }//End Start()
 
 
 
     //When I am destroyed
     void OnDestroy()
     {
 
         //When I am destroyed, remove the oldest object (me) in the list in the EnemyGenerator
         enemyGen.roadLimits.Remove(gameObject.GetComponent<RoadLimits>());
 
     }//End OnDestroy()
 
 }//End RoadLimits

You can kinda see my logic from this. This is, as you can tell, supposed to work in conjunction with a list in my AJB_EnemyGenerator script which is attached to the game object from which the enemies will spawn. The left and right limits will be the X coordinate while the game object's position will serve as the Y coordinate. My intent is to grab these variables in the other script. To use the correct one, I plan to use the list as a sort of scrolling container that is constantly gaining and losing its contents where I have an int marking a specific position in the list that will line up with the position of the enemy generator. I've been looking around for a way to do this but have yet to find anything. The code from the EnemyGenerator is shown below.

 using System.Collections;

using System.Collections.Generic; using UnityEngine;

public class AJB_EnemyGenerator : MonoBehaviour {

 [Header("The script that controlls the spawning of enemies")]
 public bool isLand = true;
 public bool playerDead = false;
 public bool truckActive = false;
 public List<RoadLimits> roadLimits = new List<RoadLimits>();
 //The number in the list that the enemies will spawn on
 public int _list;


 [SerializeField]
 [Header("These are the enemies that can be spawned using this object")]
 //Array to contain the multiple types of land enemies
 GameObject[] EnemyTypesLand;
 //Array to contain the multiple types of water enemies
 GameObject[] EnemyTypesWater;

 [Header("Timer Variables")]
 //Time variance bounds between generating an enemy
 [SerializeField]
 [Tooltip("Minimum time between enemy spawns")]
 float TimeMin = 1.0f;
 [SerializeField]
 [Tooltip("Maximum time between enemy spawns")]
 float TimeMax = 5.0f;

 //The amount of time to wait between spawning
 //enemies. Populated at spawn time based on a
 //random selection between the min and max.
 private float TimeLimit = 0;
 //Timer for counting elapsed time
 private float Timer = 0;

 [Header("The place where the enemy will spawn")]
 //These will be used to move the spawner left and right so that enemies don't spawn off of the road.
 [SerializeField]
 [Tooltip("Add the limit that cars will spawn on on the left side")]
 //This will be pulled from the road tile's spawn 
 private float leftSpawnLimit;
 [SerializeField]
 [Tooltip("Add the limit that cars will spawn on on the right side")]
 private float rightSpawnLimit;



 // Use this for initialization
 void Start()
 {
     
 }//End Start()



 // Update is called once per frame
 void Update()
 {
     //Initialize the Timer
     UpdateTimer();

     //Initialize SetLimits with a passed in variable
     SetLimits(_list);

     //See how many are in the list so that we can find the right place to put the 
     //spawn point at and then remove this!!
     Debug.Log(roadLimits.Count);

 }//End Update()



 //Change the spawn range for our enemies
 void SpawnLocation()
 {
     if (playerDead || truckActive == true)
     {
         //grab spawn limits of specific array piece
     }
     else
     {
         Debug.Log("I can't find the next spawn position to move to");
     }

 }//End SpawnLocation



 void UpdateTimer()
 {

     //Accumulate time elapsed
     Timer += Time.deltaTime;

     //Reached our time limit
     if (Timer >= TimeLimit)
     {

         //Generate a new time between our bounds
         TimeLimit = Random.Range(TimeMin, TimeMax);

         //Reset the timer
         Timer = 0;

         doSpawn();

     }

 }//End UpdateTimer()



 void doSpawn()
 {
     //Generate a new time between our bounds, but keep the enemy generator's Y and Z
     Vector3 SpawnPos = new Vector3(Random.Range(leftSpawnLimit, rightSpawnLimit) , this.gameObject.transform.position.y, this.gameObject.transform.position.z);

     //Randomly choose an index in the enemy array
     int randIndex = Random.Range(0, EnemyTypesLand.Length);

     if (isLand == true)
     {

         //Use the random index to select one of the enemy
         //types to spawn.
         Instantiate(EnemyTypesLand[randIndex],
                     SpawnPos, transform.rotation);
     }
     else if (isLand == false)
     {
         //Use the random index to select one of the enemy
         //types to spawn.
         Instantiate(EnemyTypesWater[randIndex],
                     SpawnPos, transform.rotation);
     }
     else
     {
         Debug.Log("I con't know if this is a land or water tile");
     }

 }//End doSpawn()



 //Grab the variables from the list object
 void SetLimits( int _int)
 {
     //this.leftSpawnLimit = roadLimits.FindIndex(_int).leftSpawnLimit;
     //this.rightSpawnLimit = roadLimits.FindIndex(_int).rightSpawnLimit;
     //this.isLand = roadLimits.FindIndex(_int).isLand;


 }//End SetLimits()

}//EndEnemyGenerator

The SetLimits function is obviously a bust, but that is sorta what I am trying to do with it.

TL;DR I just want to grab some variables from an indexed item in a list.

Thank you dealing with my novice code, too! I'm sure there are a dozen better solutions to going about this, but I would still like to know how to grab variables from an object in a list either way.

Thank you for your time, A.J.
