We had to switch back from a standard on-firewall boosted MC to the manual non-boosted MC on our K which originally had the ram engine and now has a 383. We did have to change the mounting plate as the castings have different bolt hole locations and spacing. I didn’t do the installation so don’t recall if there was any different hole for the rod. Seems like there would not be any choice as to which hole to use after the proper MC was bolted to the mounting plate. Don’t forget to make sure the manual MC does NOT have the little “check valve” in its snout. Otherwise the brakes will start dragging and stay that way. The firewall mounted MC for a ram car and a non-boosted Newport MC have different part numbers but the only difference is the presence of the little “check valve” and it can be punched out by removing the MC innards and running the punch in from the passenger compartment end.
I used to know the answer to this but have forgotten...(Insert old age joke here)
The 64 300s with manual brakes used a different (lower) hole location to attach the master cylinder pushrod to the brake pedal as well as a different firewall support plate than the power brake equipped cars.
My question: Do the Ram Ks use the MANUAL brake pedal pushrod position and related support plate ?
I assume they do !
