Mike, what junkyard are you going to?
There's a Pick n' Pull in Newark that at least had a couple of 240D's with intact interiors. One of 'em was even a 4 speed
According to a friend of mine (Josh; Ibe300D on here), as of the last time he went, the Pick n' Pull in San Jose didn't have any worthwhile M-B offerings...
Hope that helps...good luck!
Also, I have to ask - why is the 126 tranny different than the 123 tranny?
