Master Cylinder

Well that does shed some light on my question. The MC's are cheap enough that when the time comes to do the conversion I will by the proper MC. Since I currently have drum/drum, I'll get the MC for that application. I was simply thinking ahead for the build. I sure would hate to have faulty brakes with the wrong MC for the set-up now.

I think it would work but the balance may be a tad off. It is easier and honestly cheaper in the long run to just buy the right part for now and keep moving forward.
