So I took my 87 TII to get the brakes checked out because its been leaking a little fluid for a while but as long as i kept it topped off it has worked fine. However, the other day they pretty much gave up. So after the shop took a look at it they found where the leak was, my rear calipers (both sides) both need replacing.

Anyways, to save some money I figured I could get the calipers and the shop said they'd just charge labor if I brought them in, but everywhere I find that sells calipers for it has 2 different ones for the TII, one for "normal suspension" and one for "hard suspension". How do I find which ones I need? The car is still at the shop so I can't go out and look at it right now.

I do have a picture of the front strut, if that is the difference between the two. The one I have is the Monroe, I think gas-matic.

 

Its the most confusing thing ever, I know, but you have hard suspension.

In a nut shell, hard suspension = 5 lug and normal suspension = 4 lug. As long as you get TURBO rear calipers you will be alright. Turbe ones are wider to account for the vented rotors. Autozone will not supply you turbo calipers no matter what they say.
