I have a rebuilt master cylinder from Hampden Service Parts. The box says part number 43201 and has been crossed off and another number 40005 has been written in by hand. Here’s the question. It looks the same as the M/C that came off the car except the brake fluid outlet is at the bottom rather than the top. Anyone know what would be so close yet so far away and not work? I still have the original and a rebuild kit so I’m not out much but would like to at least ID this thing so I could re-sell it on Ebay. (where it came from)
Thanks in advance, Brian
Luck is at the intersection of planning and opportunity.
It may be off of a Buick Skylark/Special. I recall that the master cylinder plumbing coming out of the master cylinder routed differently from the Olds. You could probably find an original Special/Skylark and eyeball it to compare its M/C with yours.
We have the front half of a 62 special to use as a cowl donor and the master cyl has a squarish reservoir, a pressure switch on the top of the cylinder area and the outlet on the eng side.
