Parts are getting harder to get. NOS, aftermarket, swap meet, it doesn't matter. As the craze of rebuilding all this old stuff gets even crazier . . . parts are drying up. You almost need to stock-up if you plan on doing this for a living. I just do it for friends, etc . . . but, if you had a shop where you were really trying to pump out some work - you'd be screwed . . . no parts. Backordered. OOS(Out-of-Stock). S.O.L. !
