Dont use the stocker. Dropp that mother ****** like it's hott! I had a half bridge 12a and I use to go through ring and pinions like nothing. Granted I rompmy **** hard, but thats what its all about. Go 9" or 8.8" yeah its heavier but u will be able to launch as hard as u want and smoke evry body Tranny wise I believe u said the engine and trans is a package? If so sell the fd trans use the chips to score a TII. I don't know for sure wich is stronger but all u have to do to make it fit is swap your 12A tail housing with the TII and bam no cuttin hackig or welding. Use the 12a cross member and driv it like you stole it Final thought I have bin told by my elders that its possible to shorten the shift rods and make 3rd gear so easy to find your mom could not miss or any other noob hehehe. let us know how it goes, oh and pics.....

Then I had an 82 base but I installed a 84-85 disk rear. I broke the 3.90 and the se gears 4.09 or 4.07 or 4.11 what ever they all suck if u like to romp your ****. Now I own a beautiful 85 5 letter. This car is bone stock with 105k on it now it had 98 when I bought it. The power stearing is the only thing that dsent work. I don't know if I should fix it or swap for a manual rack. this is the first 13B car I have had since I had my drop top in 01. viva la dose-a or how bout this, fierbre dose-a my spanish sucks. Basically shane I'm a 12A man. In Hip-hop tody they all talk about old as cadilacks on 22" or what ever. That aint gangsta, gangsta is an FB with cut springs rollin on 13" with them 205-50-13 and a 12A under the hood going brap brap brap. I dont know where the **** that came from but I had to say it.

boriqua51371

yep first gens are 7" gears i personally have a ford 7.5 with ford racing lsd and mosser axels , my brother has same set up and his running 8.73 on his fb lunging all the time.

The rear end really depends on how hard you are on it. I would save the cash and give the rear end a chance, but that many ponys will rip tha 12A tranny apart!!



I know the turbo trannsmissions have one extra spline on the input shaft. I learned that the hard way! If your going to put a engine that has a turbo E-shaft in it you will need a turbo transmission.
