Happy New Year and back to the '61 brakes.......I need help again.

[TWOinLIC@xxxxxxx]

A Happy and Healthy New Year to Everyone of the IML.,

Big Red had her brake checkup and the results were better than I expected.   

My mechanic is positive he can swap my single MC for a dual MC.   He also outlined the resulting modification that would be necessary to do this.    His biggest concern is getting a dual MC that fits into the space of the original and also being able to mount it to the firewall.   Was '67 was the first year Imperial had a dual MC?   and
What year dual MC is the optimum one to put into a '61 Crown?   

As always, thanks in advance for your help,     John and Big Red
