The MC was from Doctor Diff, the aluminum master cylinder kit. The push rod was the adjustable heim joint from the same. The bore was 15/16 but is available also in 1 1/32. I believe the issue in length is probably due to the difference between a power and manual pedal being different. A stock rod might work better but I have no experience. At least the adjustable had some adjustment available after I trimmed it a bit. And it's a quality piece. I would do it again. If I could weld easily a stock rod would have probably been much cheaper to adapt though.
