So I'm working on building a exact clone (excluding Serial#) of my 1976 SP1; which means I need a lower with the .315" diameter front pivot screw hole. Does anyone make any that's not as expensive as a real SP1 lower. The reason I'm asking is because I already have the complete large pin upper.

Nodak Spud just began selling Retro 80% lowers. I'd start there.

Nope the area would be too small by about .065 and thats a lot of metal being lost for structural strength.

These are what I used to adapt a SP1 large hole upper to Nodak Spud slabside small hole lower.
