Bought a used T/C that needed some attention. Did a total take down, stock refinish, cleaning things and inspecting to see what parts will be needed. I ordered a new frizzen from RMC and a new style cock from The Gun Works. Frizzen fitted up well,the new style cock not so well. The new style cock is loose on the original tumbler approximately 1/4 in. front and back play. The old style cock is tight, but does not strike frizzen square, and is off center, would need heated and twisted which I really would rather not. Any good suggestions. I do realize a new lock would cure the problem but then my sort of good deal goes south.
