need a 904 from a floor shift car

Ok, so just so we're CLEAR as a bell, the one you need has the two bolt hole flange on the bottom of the tail shaft, is that correct?
No its 4 bolt, flat round flange that looks like its a cast part of the tail shaft. The drive shaft end just sets flat against it and you run in 4 small bolts. Which i think is odd because all others i have seen were slip yoke on the tail shaft end!
