Rear Calliper Piston Size

[turboshad]

I'm trying to spec a front and rear MC for my brake setup so I was starting with the calliper piston sizes. From what I can find it seems that the front 11" Caravan brakes I use have a 60mm piston but I can't find anything on the rear. I am using a non-vented setup from an 89 Lebaron GTC. My car is under a cover with about 2ft of snow on it so I was hoping someone here would know what size the rear pistons were. Any gurus out there? Thanks.

33mm for normal ones (10") and 36mm for the vented rear (11")

^^ This is correct. In '89 there is also an oddity. ALL G/J bodies were supposed to have disc/disc, even the lower optioned ones. What I found is that if the car had 14" wheels from the factory, it had 27mm rear caliper pistons. I had an '89 LeBaron like this...that's how I found out.

Perfect, thanks.
