1990 cutlass international

[Jscott]

hello. I have a 1990 cutlass international and the rear brakes are seized to the rotors. I’m trying to get the caliper bolts loose but they have restricted space. Especially the top bolt. I saw that Gm made a special wrench for that back then. But seeing if everyone else had an issue or could help me. Thanks.

I don't recall the space being restricted, but might have to get a breaker bar on there and a BFH (Big F-ing Hammer).
