67 442, TH400

Putting a 2004r in.

I realize I need different yoke, but how much longer is the driveshaft for the 2004r?

I was told to try to find one from a 350 or jetaway, but some of the other forum members raised a couple of questions about the switch.

Any input on driveshaft issues?

Yeah, the Jetaway driveshaft is the correct length. The 200-4R is just about the same overall length as the Jetaway and TH350. Unfortunately, there were no TH350s installed in the 64-67 cars, so Jetaway is what you need to look for.

Give me a measurement, I'll get a solid tube made!

Guess I can wait until it is installed and then take the measurement.

Thanks for your help as always.

the 442.com site also says the 4 speed shaft would be right lengh and is solid.

finding one might be a different story.....

The original 66-7 4 speed shaft was 60" center to center, with a stock 27-spline "powerglide size" GM yoke. If you use a late Muncie or Super T10 that takes a T400 yoke (32 spline), 59.5" is correct and 65-70 Bonneville shafts are 59.5", one piece tubing, with a Turbo 400 yoke on them. (This is just to add info for other readers).

I would get the engine/trans into the car first and measure using the yoke you plan to use on the driveshaft. Pull the ooke 1" or a max of 1.25" away from being fuly inserted into the trans, have the car at ride height, and measure the distance between centerlines of the universal joints. Then you know the shaft that is made will be correct. Remember that Olds uses a bigger u-joint than Chevy. Olds is about 3.62" across the cups, and is a stronger joint, about like the Spicer 1350 (but not interchangeable).
