The more I keep digging into this car the more mess I find. I was gonna measure the distance between yokes in order to buy the drive shaft when I started having doubts about the rear end. It doesnt look mopar to me. There is no yoke on it and it doesnt seem to be 8 3/4 rear end judging by the rear cover and its shape. If someone recognizes this rear end please do tell cause Im a bit lost here.

Just a thought, if it is in fact a 8" Toyota axle it should be strong enough for a cruiser. Problem is I guess that your stock Chrysler drive shaft you bought will now be too short. I wonder could you have a drive shaft modified to use the Chrysler slip yoke on the trans end, and the Toyota bolt on flange on the other?

I agree it looks Toyota, most likely a sure grip type from a 4x4 swapped in for the sure grip. Wonder what the gear ratio is? You might figure out the ratio etc by turning an axle and counting rotations of the input shaft. I wonder if the bolt pattern is the same as Mopar, it would be a complication if the bolt patterns are different from the front wheels.
I found an 8 3/4 rear end in germany but its quite expensive. I might just try to make it work with this one. Ill see what the bolt pattern is and try to figure out the ratio.
One thing that keeps confusing me though. People keep talking about 50 inch or so drive shafts for the c bodies, or 44 7/8, and the distance between my 747 and the rear diff is considerably more than that, probably close to 3 meters which would be about 130 inch. Is that the lenght of the one section only or am I missing something else here?
Thank you all for your input guys. Much appreciated.

Can't help much with drive shaft length or type. My '70 uses one piece drive shaft with the length defined as the distance between the center-line of the u-joint bearing crosses at each end. Yours is probably two piece with a center joint. I say probably because all 67 automatics got two piece, but manual tran cars got a one piece shaft. I imagine there are damn few 67 NY'ers with manual shift. If you use the diff you have, you will need a custom shaft, so it might be easier to make it one piece.

My bad, instead of two piece, I should have said automatic trans cars used inertia yokes. The two piece drive shaft with constant velocity joint was used on the Imperial
Right, Ive been digging around the forums a bit and found a moparts drive shaft chart. There is no Ney Yorkers on there but according to that chart there are only two options of drive shafts for a 67 model with 727, 440, 8 3/4 combo. One is 52.27" lenght, 3.25" diameter listed as a Charger shaft and the other is listed for Chargers, Belvederes and Coronets, 51.15" lenght and 2.75" diameter. There is one more, a longer one but for 68 models.
I think I might have overlooked the fact that merc tranny is a whole lot shorter and that the 8 3/4 rear end has a pinion yoke sticking further out than the Toyota rear end. That should account for roughly 50 inches which would put the lenght right in the ball park.
