Nobody owns a BB with a M35?

Keith -

3/8" is the size of a PCV pipe on the carb base - there's no way a correct modulator line would be the same size; I'd expect it to be more like the size of a brake line (3/16"-1/4").

Keith -

I know that - I was just referencing the size as a comparison; I can assure you the original modulator line was NOT 3/8".

Alright thanks. I guess the one that came with the car was home made. I know it spent some time at a trans shop in the 70's.
