1972 master cylinder to power booster seal and retainer

[Larry M.]

Does anyone have photos of a 730392 seal and a 9787620 retainer (both in grp 4.910, and in section J50 of the AIM) that they can post? Application is for 1968 to 1982.

Larry,

Did you find a source for the above seal and retainer? I am looking for them also.

Thanks,
Allen

Allen,

No, I did not find a source for them; at least, not the retainer, but possibly the seal.

After having no luck at any of the normal vendors, I found this: https://www.c3vr.com/vrforums/master...age421197.html

which led to to believe they weren't needed, so I stopped my search.

I did get from ZIP a DB-516 foam seal, but I can't say for sure how close to original it is, as our car had a replacement master cylinder installed so any originality was gone.

FWIW, I installed a new repro master cylinder onto a new repro power booster (using that DB-516 seal) and the car stops just fine. So far.
