So, mother mopar in her infinite wisdom, used studs thru the MC that had nuts on the inside.....on the bottom two bolts for the master cylinder. I call foul. Mine are rusted out and not tight. So, new at high price, or epoxy them into the MC. I am going to go a different route here. The new MC bolts fit fine....thx for that. But, I am going to use the two top studs to hold the MC in place, and then, I am going to get two 5/16 grade 8 bolts, ensure they fit thru, then use something to glue them in place from the inside. Prob will not use JB weld epoxy, but prob gorilla glue that could be removed if desired later. I will push them thru from inside, and add nutz from the outside, and let the glue harden. The h*** will the mopar demented dream.....sorry.
