have been slowly bringing my 88ss that i got a year ago back to life. Now the brake calipers have froze om first the front now the rear. Have a donor car 84 Turbo . The calipers look the same but when i put them on had to force and now they seem to be very tight holding all the time. I was told that the calipers for the 87-89 model s are different than the 84-86 just need to know from trhose who gone this path before me is this true.
