According to earlier posts I've read in this section, the one and only correct master cylinder for 70 e-body disc brake cars is the 2229171 casting, which is apparently nearly impossible to find.

Are there any other options out there that are semi-correct for this application? I'm not looking for concourse correct, just something reasonably close to correct that won't break the bank.

I see that Bill Allphin has one listed for 1970 B and E body cars (Part No. 38263). Would this past muster? Any other options out there?
