i think it will fit but after he said that i just want to make sure. thanks

use 33 moser we have ran 1000 plus hp with them for years

from 3780 lbs car to 2900 pounds

x2,dont get more than you need.i know a brand x guy still runnen 31 spline in a 2500# door car goen 5.80's.

I was gonna just keep the 31 spline locker that's in it but its a scj rear so I could rebuild it and sell it and I already gotta upgrade to mosers so I was just thinkin goin to 35 spline. My car is a 4 speed and plan on doin a 10.0-11.0 comp. 557 with p51s and my low rise dual quad or victor if I can fit under a stock hood so I think if I can get 1200 for my scj 3rd member and I already sold my stock axels why not just get a 35 set up. Axles from moser will be the same price, a locker will be 585 or so but I'll need to get gears case etc. Or spend 1600 and get one from moser. All set up. Haven't decided if it cheaper to do that or or go get stuff from jegs and forum members

I vote for the complete package from moser.

I respectfully disagree. I'd overbuild for future growth, the cost difference will be negligible. The knowledge that you aren't going to break it is priceless.

yep,if your gona buy a new chunck anyway i'd go 35's too.it'll all cost bout the same and you wont break it,the 4 speed may be another issue.
