Technical Upgrade Master Cylinder on 54 Chevy Convertible?

Anyone put a dual reservoir master cylinder under the floor in a 1954 Chevy convertible? My car has the stock 3 speed with 235 engine. I need to upgrade this to match up with front disc brakes,etc. Cannot find any info or kit for the convertibles.

have you checked out ECI they have a kit that lets you still use your clutch pedal

No, have not checked ECI, but will. The convertible has a huge x crossmember and a wider m/cylinder does not look like it will fit. National Chevy listed a changeover kit for a short time that used a Mustang remote reservoir cylinder. It was listed as out of stock. When I called them, was told it was no longer available. The guy would give me no info as to why, etc. Evidently it did not work out so well. I do appreciate any and all advise you guys give me.

I did check ECI, they have a setup for 53-54 chevys, but will not fit convertibles.
