I've been looking on google ever since my first post.
You can call Denny's Driveshafts. You need a counterbored 32 spline th400 slip yoke.
It should be a 1330 but they don't list one, you might need a crossover u-joint.

Yes tell them what you're doing. A crossover u joint has, in your case, a 1350 to fit the yoke and a 1330 to fit the driveshaft. In other words one u joint has two different size caps.

You need one for a threaded shaft.

Since no sponsors have stepped up to help...
Slip yoke is specifically designed to be used on a T-400 & 4L80 with the Threaded Output shaft. This design will replace the truck style bolt on yoke with a car style slip yoke and allow for proper slip travel and bushing contact for best performance. A must for any threaded output shaft on T-400 & 4L80 transmissions. We designed this yoke to solve this problem over 25 years ago

You need the counterbore to allow the yoke to slide over the shoulder on the shaft to maintain the proper spline/tailhousing bushing engagement.
Some 4L80E's and a lot of 4x4 transfer cases use the same yoke but fully splined. They don't have the o-ring or the shoulder that the counterbore slides over.

the gentleman does need a counterbored yoke, Denny's can get it for him, it is the TH400 for threaded output shaft yoke.
You would think with all the high speed trans vendors on this site, they would know this.
However,
Not all TH400's have an output shaft like that.
The truck units that used a bolt on yoke have a similar output shaft, the Denny's slip yoke will work on both the TH400 and 4L80E. The TH400 bolt on yoke is too short to use on the 4L80E in a truck application.
The older passenger car TH400 shafts are splined slightly further up the shaft and don't use the o-ring as shown. They use a regular, non-counterbored yoke.
The TH400 truck shaft has a raised ring around the o-ring area that will cause a regular non-counterbored yoke to bottom out. Hence the need for the counterbored yoke on a retrofit application.

I was wondering if i can use to stock slip yoke that came with my 80 and get a combination U-Joints 1330-1350 if im correct the 1330 is the stock camaro size and the 1350 is the size for a 01 3500 chevy work van. I also got the stock flex plate and converter off the van will it work with the camaro if so will i still need the spacer for the converter.

The shaft has a threaded hole but I didn't half to unbolt it. Do you know if the stock flexplate and converter off a 01 3500 van this is what the 80 came out off will it work in my camaro without the spacer for the converter or are all the parts different? thanks Brandon
