In the info library there is a listing for a brake master cylinder that says Wagner F37073 TRH29. I have a replacement MC in my 64 that has a cap that sticks up so high that the cover won’t close over the dash opening. Any suggestions? I’m not sure what type mc it is, or if I should relieve the cap enough to get the cover latch to close. Could grind the plastic cap and then heat seal it so I don’t get leakage when fluid gets hot but would rather get the right part.
