I picked up an 84' Trans am that I'm rebuilding, but I'm curious as to what rear end it has?

7.5/7.625" 10-bolt, very weak. Or are you just asking for the ratio?

Your original gear ratio will be on the rpo sticker, if 84 models had this. But ratio would be one of the following GU2= 2.73, GU4= 3.08, GU5= 3.23, GU6= 3.42, GU7= 2.77
