i used two different sets of gaskets. both, i think were in the $6X.00 range.
the Federal Mogul set was not as complete and was missing things like touch control pump gaskets. The Victor Reinz set #FS1879X (from NAPA) did (both ends!).
NAPA did carry ring sets, but i don't remember what i paid.
I took a look at Joe's Farmall, from Georges post. Looks like he's got a pretty good selection of commonly needed parts. i'm going to give him a try on a carb kit, muffler, and decals.
