need help here guys. I want to hear from guys who have done a dual master cyl conversion on their 49- 51 mercs. mainly did you use a kit and was it simple. or did you go with something that bolted straight to the same place as the old cyl and used the stock linkage. I would like to put it in the same place as stock and use the same linkage and have heard it can be done I don't want a booster. all info will be greatly appreciated. thanks
 
A simple right angle bracket from ECI brakes (don't know if they still carry them) and a mid to late 60's GM drum/drum master with built in residual valves.

just went to their catalog seen the spacer 220.00 bucks a bit out of my price range.

Suspect that you are looking at the wrong thing.
As I said they may not have them any more.
Call them to see if they still make them.
It is nothing more than a right angle adapter that bolts into the original bolt holes on the side of the frame and provides a mounting surface for the dual master.
If they don't have it try swap forum it may still be available

yeah 51 merc that was a different dog than what you show.the piece you show is what I was thinking it should look like. thanks for pic
 
I used the Fatman bracket on my 51. It uses the stock mounting holes and raises the master cyl. higher than stock. With a 351 Windsor I had to use a heat shield. The stock push rod is shortened aprox. a inch but you still have to fiddle with it because of the location of the large adjustment nuts. Glad I did it.
 
oldsman41... I used 77 Mustang master cyl. Raybestos # mc36440. It is for a manual disk/drum system. The fittings are on the opposite side which is what I wanted.As far as the heat shield it isn't nessesary but with the stock 351 Windsor exhaust manifolds I thought it was a good idea. The master cyl. stays nice and cool. Probably not necessary with a flat head. Call Fatman for info.$65.00
