Try these guys for points, cap, condenser and rotor.

www.mcdonaldcarb.com/category_s/23.htm

My suggestion is just to find another American-Bosch MJK 4/2 360 series mag that has the cap and rotor (and maybe serviceable points and condenser too) and swap the parts over to your mag to fix it.

If you go with all new parts, you will have a nice mag but very expensive repair, in my opinion.
Cap DP52469 new is $84.00 -- still needs carbon brushes to be complete (BR521004AS Bosch Brush MJK $5.95 each and you need qty (3))
Cap gasket GA 52148 new is $5.40
Rotor RT 52154PA new is $77.00
Points BK 52234AS new is $24.24
Condenser CW52110AS new $10.90

Better to salvage and fix, much cheaper.

The rotor assembly is now in two pieces. the gear is on the shaft but it twisted off just behind the bearing, so I will need rotor assembly and bearings or another mag. The mag is a mjk4/2 360c 47. I forgot who said they had one but if you have pictures and a $$ amount please let me know. does anyone know why it would break the rotor shaft. I talked to a magneto shop in Ill. and they said something in the pony motor causes the shaft to break. I did fine the crank pulley nut was loose . could the crank end play cause it to break the rotor shaft in the mag???
