please help me.

i own a 1981 rx7 that has been running on a bad OPEN diff for over 4 years.i decided to finally fix this and went to the junk yard to pick one up.to my surprise i found a 1984 with rear disks and LSD.i was able to remove it completely with almost new tokiko shock absorbers all for 110 dollars.today i removed all of my rear suspension along with diff,everything seems that will work ,


EXCEPT THAT THIS DIFF HAS A DIFFERENT BOLT PATTERN ON THE DIFFS FLANGE.4 BOLT BUT WILL NOT MATCH MY DRIVESHAFTS BOLT PATTERN?WHAT CAN I DO???
IM DONE FOR THE DAY,I GOT TIRED OF WORKING ON THE CAR.WILL THIS HAVE DIFFERENT RIM SIZE??4 X 110 IS WHAT IM RUNNING....

 

go back and get the driveshaft out of the same car. the bolt pattern on the pinion flange was changed in 83 or so.

 

THE CAR THAT THE LSD CAME OUT OFF WAS A 1984 WITH AN AUTOMATIC TRANS NOT A MANUAL.WILL THE DRIVESHAFT BE SHORTER OR LONGER.ALSO DOES ANYBODY KNOW IF IT MATTERS IF A LSD IS OUT OFF A MANUAL OR AUTOMATIC GEAR RATIO WISE>>>>WHATS BETTER.

 

THANK YOU BUT I NEED A LITTLE MORE HELP..

 

hmm...

 

Same Gear Ratio. A/T or Manual Trans.

 

Check www.grannysspeedshop.com for specific ratio.

 

i think you have to get a 5 speed shaft.

 

No it doesnt have to be a 5 speed shaft. I just did the swap last week. LSD from my autotrans to my manual trans open diff car.

 

oops. yeah you prolly do need the 5 gear driveline.

 

Youll need a manual driveshaft. Or you can swap over the yokes. But be forewarned, I dont reccomend this, although many others have done it without any problems.

 

so for sure it has to be from a five speed tranny.....the drive shaft....thankx for all the help you guys..the rotary kicks assssss......= - )

 

yeah it has to be from an 83-85 too.

 

lol

 

was up with the cap pic???

 

Flange is different, so is rim bolt pattern, and I think that the brake line thread is different.

 

uh, no.

 

I thought autos were all open diff

 

I don't think GSL-SE's came with automatics.

So assuming it was a GSL automatic than you still have the 4x110 wheel bolt pattern. The brake lines will work just fine. All you need as already mentioned is the driveshaft. You did get the e-brake cables with your rearend right?

 

lol you were typeing LIKE THIS... ITS ANNOYING

so he put up a friendly reminder where the caps key is lol.

 

i did get the parking cable complete with brake handle.the lsd diff is installed in the car , i had no problems installing just the flange pattern....im going to the junk yard tommorow...
