Z145 Prestolite Rotor, can't locate supplier

[sideout]

I have a MF202 Workbull that someone put a Z145 engine with a Prestolite distributor into. I can't seem to locate a Roto cap for it. The massey/agco part number is 1047223M1, I know this is correct since I still had the box from the last one I bought 12 years ago. I found that my dealer can get it (1hr drive + $56 + tax). Please help me locate a cross-reference or cheaper supplier. I'm going to sell the tractor.

Just in case some else lands here. Go buy a rotor for a JD 1010. Part Number AT14680.

NAPA also handles them: NAPA AUTO PARTS Copy and paste the Massey part number to the 'find a part" box top left. Be sure and check the little interchange box. It shows my local NAPA has them for $13.05.
