The price is $20.49 according to thier price list. I think I paid about $12 or maybe more from one from NAPA for a NV3550 to an '03 block. I think for a limited application, that price isn't to bad. Of course there is shipping. AA is a bit more expensive on their items, but for limited production pieces and specialty parts they really aren't over priced. Why not see what a machine shop would cost to produce the part. Then maybe AA prices won't seem to bad.
