[Supras] Frozen calipers - best options?

[Suprarossa at aol.com]

All four calipers on my "new" 1989 Turbo are frozen, which shouldn't  be a 
surprise considering how many years it had been sitting before being  rescued 
and brought into my stable. What are the Supra Gurus suggestions to get  
reliable calipers at a decent price? Repair, replace (and with rebuilt or new)?  All 
I've found so far in searching is a company named Cardona (or something  close 
to that) with rebuilt calipers for $90 each. But they only have the fronts  
available. Why not the rears?
