Anybody know the part # for stock GMC Master Cylinder rebuild kit?

Also, when I first got started in GMC'ing, I was told that there was a difference between the 73-76 MC and the 77-78 MC. Is there, and if so, what is the difference and does it effect rebuild kit?
Thanks

OK, FYI. I was able to get the PN for the stock GMC MC. It is RAYBESTOS MK646, and is available on eBay and at Rockauto. Interesting enough, my local parts houses do not have a listing for this number.

AND, anyone....Is there a difference between the 73-76 MC and the 77-78 MC and if so, what is the difference?

Thanks all.

Whoops...let me clarify that. The number RAYBESTOS MK646 is for the REBUILD kit, not for the whole MC..Sorry about that.

Didn't Albert Branscombe do some research into the later MC? I recall it being discussed here a few years ago.
