Another data point for the research - my car - 1968 L34 with THM400 has the yokes in-line

Thanks for the input - another BB car (L34 396ci/350HP - SS only) with TH400 and in line yokes.

As appropriately referenced in a previous post - a limited amount of data to draw hard conclusions from - however, there seems to be a trend developing here.......

BB cars w/TH400 have driveshaft with in line yokes, everything else offset yokes.

I say again, what the h _ _ _, over?

I just replaced the U-joints on my '69 L-48 car.It has the offset driveshaft.It orig. came w/ TH-350 tranny, but has a date correct TH-400 from a big car.Not sure when it was swapped but an owner from 1982 says it was like that when he got it.It seems to work fine w/ the TH-400 and dosen't look like it was cut and shortened.

The TH350 trans is shorter then the TH400 trans by about 4". The shaft had to have been cut. Maybe it's a factory shaft for a Th400 with offset yokes. If it is the Th400 inline theory may have taken a step back.

I put a THM400 in my 67 I used to have and only had to put a 400 yoke on my PGlide driveshaft (and a new flexplate...and a different starter...and a crossmember...and a shifter). Didn't pay attention to if it was offset. That was about 20 years ago.  ;)

RamAirDave,

RE: Picture of your drive shaft.

What was the build date of the car this came out of?  Was it a Norwood car? About how wide were the paint stripes, and the stripe location down from the approx centerline of the front yoke?

Thanks,

Camaro Billy

Here's a shot of the whole thing.Hard to see, but if you look close you can see the offset
