Alright, there's a long brace that goes from the AC Bracket to the manifolds on stock engines that's there for needed bracing, my problem is that when the previous owner switched to headers, that brace was taken off and not put back on and now my AC Compressor shakes really bad and getting worse because there's no extra bracing to it.

How hard would it be to fab up a brace to another part of the engine from the AC brace?

 

a piece of steel and drill holes in it

not difficult

get creative

 

Rod stock, flatten the ends, bend to fit, drill, install.

 

or get a stock brace and make a spacer out of a piece of pipe to use a stud assembly like the factory manifold did
