I figured I'd give a shot here, in case anyone has these pieces sitting around or in bulk - hoping to find someone that can drop them in the mail, rather than pay more in UPS rates than the parts cost.
Needed:
IP gov shaft bushing - stumpy 19mm version
Viton O-ring, 4x7mm
Crush washers: (2x) 6mm
(2x) 8mm
(5x) 12mm
Thanks!
