Does anyone have the correct part numbers to take to a driveshaft shop for the conversion? The early valiant barracuda site shows this:

Here are the Spicer part numbers
for the B&T conversion.
Flange2-2-349
U-joint5-153x
Slip yoke2-3-800kx
Spline2-40-1711
Tube2 1/2 dia / .083 wall

The problem is NOBODY has any idea what a 2-3-800kx slip yoke is. Do you think it should be 2-3-8001kx?

Thank you.
 
I just did a bunch of research and I think it is 2-3-8001kx. Ill post pictures of parts and the finished shaft with dimensions in a couple weeks.
 
2-3-8001kx is what I came up with, too. The other number was a typo that got repeated.

I look forward to seeing photos of your conversion. The same thing is on my to-do list.
 
I'm pretty sure the number is 2-3-8001kx . That write up is my 66 Cuda. I will have to try and find my original invoice, to verify. But that might take some time, as it was about 2002

Just looked up those parts. WOW have prices increased. My complete driveshaft was right around $100 complete, parts and labor. Had two made, one for the 7 1/4 rear, and one for the 8 3/4.

Any 4x4 shop can make one up for you. may have to drill an output flange but the rest is stock stuff.
 
I took all the parts (and yes it is 2-3- 8001kx) to a driveshaft shop today. the 2-2-249 flange fits directly into the 3 5/8 pilot diameter on the tail flange. My shaft spec was 55" from the rear facing surface of the tail flange to the centerling of the rear u joint. Probably no two cars are the same. I will post pics when I get it back next week. Should be no drilling required.
 
OK here is a cut and paste of my post on the valiant barracuda site. I have included ALL of the necessary part numbers:

I just bought all the parts for the conversion and dropped them off at the driveshaft builder. Several things:

1 - the part number for the slip yoke is incorrect in the tech how to section. The correct # is 2-3-8001kx.

2 - You also need to buy a rear weld yoke and conversion u joint for the rear if someone is making you a shaft.

The correct part # list is:

2-2-349 flange yoke (front most part)
5-153x front u joint
2-3-8001kx slip yoke
2-40-1711 spline
correct length of 2.5" .083" wall tube
2-28-367 weld yoke
5-788x u joint (this u joint makes the transition between the new rear weld yoke sized for a 1310 joint and the 7260 size at the rear end pinion yoke).

All part #'s are dana spicer and easily available from places like denny's driveshaft where I found the lowest prices by far.

Having your shaft built with these parts gives you an easy bolt in fix. Work with your shaft builder to make sure what you're measuring for overall length is clear. I worked with shaftmasters near dearborn MI.

I picked up the shaft and installed it. Drove the car a bit no issues no vibrations. It is difficult to get a tool on the 9/16 hex of the 3/8-24 nuts to hold the new flange onto the trans tail flange. I have parts coming to restore the old trunnion shaft for a spare.
