Hey everyone~ I just spent the last 7 hours under my 36 chevy making the cross member that is going to hold that tailshaft of the TH-350 that is mated to a chevy 305 V8. I figured now would be a good time to pull the master cylinder and make new lines.... a previous owner of the truck already got into this thing and changed alot of things around, I feel that might be the case with this MC. the only numbers I can find left on the MC is "A1382" does anybody know where / what this thing came out of. it's an old cast piece with the pivot point for the brake peddle built into the unit... it has only one brake line going to it that exits directly rear of the MC. please help ~Mykk
