Eric,
My application is an 1800 race car that has a transmission based on the M47. Not an M47, but a Swedish made dogbox specifically made for racing. The motor is a B20. Hydraulic clutch that was used in a 740.
The bell housing that I have, PN 1023519 that came with the car I thought was for a 75 240.
I found what was listed by a salvage yard as a 75 240 bell housing and bought it. It does NOT have the sleeve through which the transmission input shaft is fitted. It DOES have the sleeve for a hydraulic clutch. Has a weird PN -- 2W 812188. And it does fit an upright red block. But maybe it was from a B21.
So, here are my questions:
1. Are these both from 1975 240s?
2. If so, what was the difference between the cars they came out of?3.
3. Did some 1975 240s have M40/41s and some M45s.
I know little about the Volvos after 1973. B21 is like talking foreign language to me.
Jim
