All, this thread is the Gift that keeps on giving.
Using NAPA Dual Master for 67-69 Pontiac Bonneville
for Manual Drum Brakes.

The original pushrod on the Single Master
was held into the rear of the master with a
snap ring. There is no provision for a snap ring
or clip to connect to dual master.
The push rod ball end fits into the bevel
of the new master but,

Question,
Is there a different rod that needs to be used
or will the brake pedal itself hold the rod in place?
Also, will it matter if I use the original 1/4 inch 64
Brake Lines , or do they need to be 3/16
like the 67-69?

Thanks
