Brought this back to the top... Thanks Jckkys.
Contacted the
musclecarresearch.com folks and they gave me a couple of options for my H block rebuild. Once I found the number under the block it confirmed which kit was correct from the ones they suggested. I bought two, one for spare incase of, you know how things can go.. $21 and change to my door. Piston was off center, but the warn light bulb was burned out.
It was a bitch getting the piston out, now I just need to clean the parts and reassemble per their directions.
