yamaha 1975 mx 250b parts interchange INFO needed

[lafeet]

Hey All

i recently bought a 1975 mx 250b (thought it was a yz till i checked the #'s)

anyway i have a 1974 125yz and i know what can be interchanged on that model but the 250 i'm not sure about.

so if anybody out there can give me some good advice about what i can swap on the 250, like head cyl, crank, gears, ETC. and the years and models that are swapable, it would be a great help.

i have a yamaha cross referencing program but its not being much help
which does not mean a whole lot in some cases.

thanks ahead of time for any help you can give me.
tks
jerry
