360 Magnum engine

Unless they changed the rules for rear ends in stock Eliminator. You are not allowed to use a truck rear end.
The way to tell the difference between the truck and the car rear end is the truck rear end does not have the mount for a pinion snubber.
Don't quote me on that but that was my understanding of the rules.
I think when they say no truck rears they mean no floating hubs (8 lug wheels), might be wrong. Especially since there was no production Dana for an a-body.
