Hey guys need some help identifying proper strut housings for 1980 LSD conversion. I have a GSL LS rear end and found a place that has the struts complete with calipers and rotors. I know the later model ones are shorter and have a bigger inner bearing. What are the dimensions? Any other tell tale signs? I guess rotors would be 4.5" stud holes or 110mm right? Any caliper tell tales?
Thanks

 

You have your #'s and letters a little mixed up. The GSL and GSL-SE both had the LSD you're looking for. The GSL has 4x110mm bolt pattern like almost all 1st gens. The GSL-SE has the larger 4x114.3mm (4x4.5"). The GSL-SE also has studs, where all others use bolts to mount the wheels. So an easy way to tell is if it has threaded holes for the regular bolts, or if it has studs or non-threaded holes for studs.

 

GSL has solid rear disk rotors, while GSL-SE has vented rear disk rotors.

 

Ok that's good to know since I have a set of Konig Rewinds i bought for the 80... now do i need to replace the brake lines or are all GS, GSLs the coarse thread? Also do I need to replace the front strut housimgs and calipers?
