Do GSLSE rears bolt in to 1980 rx7s?
 

Do they? My 1980 rx7 has a bent axle and I would really like to have the lsd. If its a bolt in I'd rather just go with a GSLSE rear, otherwise I'd probably go with something stronger.

thank you.

no. the SE has larger axles and a different bolt pattern. best bet is to swap in the rear from a gsl that way u retain the 4x110 pattern.

to do the swap properly, you'd need the complete SE rear axle, fron spindles and SE wheels.

The rear end is a direct bolt in, but then you have the issues mentioned above.

also the brake lines needed to be upgraded to the gs or the gsl or the gsl-se the pitch thread on the brake lines is also different...but everything still bolts in just fine...

Its a super easy swap so don't start trippin thinking its a lot of work when its not...

I did this swap many years ago. I recall swapping the brake master and proportioning valve as well. To keep the 4x110 pattern, the axles were re-drilled, and the wheel studs moved over to the new set of holes. If running 13" wheels you may have issues with clearance over the SE caliper. My old 13" meshies cleared by a small fraction of an inch.

Thanks everyone for the info. I really appreciate it. I'm not worried about the lug pattern because I also need new wheels as well. Also All the brakes and brake lines need to be replaced so I'm not concerned about that either. I guess what I should have asked is whether the suspension is the same.

Correct me if I'm wrong, but the GSL-SE lug pattern is the same as 4 lug mustangs right? If so my a friend of mine will already have a set of wheels for me, assuming the offset is close enough.

Thanks.

Yes...SE is the same as 4 lug mustangs

They don't have the same bolt pattern. Mustang wheels will not fit.
They SE has a 4x114.3 bolt pattern (4x4.5), and the 4 bolt mustangs are 4x108.

You are right...I stand corrected!

i have the complete gsl-se suspension in my 79. its really easy but you will need everything from front to rear,

you will also need the drive shaft

So if you use a GSL-SE rear I am guessing you need the GSL-SE driveshaft!!?? Will that fit without modifying the shaft into an older SA using an SA style trans? Also if you upgrade to a turbo II tranny...does the driveshaft have to be modified then?

I think you can blast the nut off the rearend plate where the driveshaft attaches to and swap out just the plates from rear to rear so your orginal driveshaft will then match.

I say "I think" b/c I just did so with my 85 GS to GSL-SE rearend swap but your doing a SA to GSL-SE...?

And yea you have to get a custom driveshaft for a TurboII transmission to a 1st gen rear. Front being able to fit the TurboII spline in the transmission and rear being able to mate to the 1st gen rearend. It's not that expensive if you take the task to a compentent driveshaft shop. Over $200 and you're getting yanked.
