small block oil filter adapter

The gasket kit is P5249320 and the bolt is P5007515. I got about half dozen gasket kits and 2 bolts....and the bolts are around $60 unless you go to Jegs, then its $81.99 :angry7:
Man, I need to find a way to machine some of those! I'd probably make a killing at $40 a pop! 8)
