57 3100 4-speed Disc Brakes

[Ghetto Fireman]

Hello All:

I have a 1957 3100 with 4-speed manual transmission. I’m adding a drop axle from SIDS along with 2 1/2” dropped front leaf springs. Planned on upgrading to discs up front but I’m finding out that the kits available won’t work with a four speed manual ? Does anyone know a solution to this? Can I go with a non- booster master cylinder? It’s my understanding that the 4-speed transmission cross member interferes with the frame mounted master cylinder. Anyone done this conversion?


Thanks

Mike
