I'm fitting an early 83 GSL diff and brakes to my RX-2 and need a little help. I'm using the RX-2 Axle unmodified.

1.) what fluid do I use in the GSL LSD?

2.) Locating links look the same as the RX-7. Anybody know if urethane bushings for RX-7 will fit the RX-2 links? What's the ID and thickness of the locating link ends? I can measure mine to see if they'll work.

3.) Rebuilt calipers - My current calipers have blown piston seals and the piston face is destroyed by too many kids with pliers trying to replace pads. If I get reman calipers, will the piston be new and un-destroyed? Where's the best place to buy calipers without spending too much?

 

you use standard SAE 90 weight but that is formulated for limited slip differentials.

 

How about rebuilt calipers? Do they usually get new pistons, or are you just as likely to get another chewed up pair?

 

I dot know what happened to my post lat night. so here we go again.

the 81-83 GSL 3rd member is a straight swap to a RX-2.

For the front calipers, you can try using a SA front brake calipers as I did it in my recent RX-4 project. I also know a good shop here in LA that can rebuild them including the brake booster (you may as well get that done also). Im sure I have several calipers from those vintage rotaries. If ur interested, i will look for them and see how it will cost to get them rebuilt....just pay for rebuilt costs/shipping + I need your old ones for core.
