8.8 swap

Well that sucks i guess til i get the disks on it. It's actually less than an1/8th of an inch of play. I have good disks up front, just wasnt sure of the disks swapping onto a drum rear end. I only picked this one because it had the lsd, the axle with disks is an open.
I had no problems with stoppin before, i just wanted a good limited slip and my 8 3/4 -489 worn out sg would have cost 5 times as much as an 8.8 swap, to rebuild and get disks on it...

If it's less than 1/8" of side to side play I doubt it's a problem but you could always pull the rear cover and inspect things to ease your mind. As mentioned earlier C-clip differentials have some side to side play. It's there but less noticeable with disc brakes because due to the design discs hold the axle in place better. Plenty of guys run cars with drum brakes on the rear. Seems like nowadays so many guys talk like if you don't have 4 wheels discs your car won't stop good and that's simply not the case. Do discs work better, sure they do. Does that mean drum brakes are junk, absolutely not!
