I have an '80 Malibu wagon I'd like to do this to, where did the adapter plate on the firewall come from? Any chance you could show the dimensions or a blueprint of it?
Is the adjustable pushrod a necessity if using an OEM manual master cylinder?
I used a plate of my own design, but I based it off of this one.
The disign in the link is based on the original design.
My design "tightens up" the specs in the link and takes out the "slop". There is no adjustment needed in the plate I designed. It bolts to the firewall and aligns the master cylinder to the push rod attached to the pedal. My design also has an integral pushrod retainer (keeps the pushrod from falling out the back of the master cylinder).
An adjustable pushrod is not nessesary, but it gives a lot of extra adjustment and it will take a lot less time to get your manual brake pedal set up and working correctly.
Let me know if you have any additional questions.
