Malwood underdash hydraulic kit for A-Bodies
I was reading through the comments a bit. I get the reluctance of having the master under the dash, but for idiots like me it saved sooo much fab time with making the AP or similar kit mount correctly with enough backing for flex on the firewall, the math on the pedal travel, pedal stop, etc etc. The cheapest way to do this is buy the Malwood and the Ram bearing, they pop up on sale on amazon for $220 every now and then, that is all you need. Modifying my power brake pedal was quick and easy, and I sold my manual pedal assembly I had sourced as it was not needed anymore with this kit. I had already bought the AP kit two years ago so I ended up using the Hydramax bearing as I had no takers on the kit.
I have to add, Ross at Malwood puts on a master class of tech support. He will call you back and has no problem explaining things and answering all of my questions. Malwood and Brewers tech support has been amazing helping me through this swap.
