I would like to convert my 240D to manual steering. As everyone knows, W123 manual boxes are like a needle in a haystack. Seems W115 are a lot more common.

I am capable of fabricating parts, but do not want to do anything crazy.

What I really need to know:
Will a 115 box bolt up to a 123 frame?
Will I be able to use the 123 pitman on the 115 box?

I suspect I can custom fab something to make the steering shaft work if needed.

Thanks in advance!
