alrite i need to know what size rearend is in the 94 z28. is it a 8.5? does it have a c-clip? is it a 28 or 31 spline? and whats the stock gear set? i need to know this case im looking into getting the rearend rebuilt with a powertrax no slip traction system. any opinon on that is welcome to. thanks

 

There are 3 stock rear end ratios, depending how the car was ordred. 2.73, 3.23, 3.42. AS for the rest od the information, there should be information eiher stamped on the front side of the right axle tube or on a tag attached to the rear cover. You would hope that whorver is doing this job shouls be able to figure this out. Otherwise you could be in trouble.
