Okay so If I can’t locate a stock driveshaft I’m gonna have to make my own so I know I’m looking for a 48 inch driveshaft but what u joints do I need for it

I've bought new shafts for my last 2 bracket cars. The '68 Bird needed a 49" inch shaft. They're measured from center of u-joint hole to center of U-joint hole. I put the slip yoke into the trans, leaving it backed out about 3/4". Then I measured from the center of the U-joint hole in the pinion yoke, to the center of the U-joint hole in the slip yoke. It measured a hair under 49".

So, I ordered a 3" diameter 49" PST shaft. It came with the Chevy 1310 series joints, on both ends. That's what I needed on the rear, since I had a factory 12-bolt Chevy rear end. But, I had a Pontiac slip yoke. So, I had to order a 1310 to 1344 conversion joint, for the front. The Pontiac size joints are also called S44, & GM 3R size. So, 1344, S44, & GM 3R are all terms for the same size joint.

If you want one of these, in a 48" length, it's part number 310480. Here's the best price I can find. Today, it's $156 shipped.

https://www.ebay.com/p/Precision-Shaft-Technologies-Steel-Driveshaft-48in-Long-3in-Dia-310480/657343687

If you have have a slip yoke & pinion yoke which uses the 1344 joint, then you'll need a 1310/1344 conversion joint. There are several brands available. Back in the old days, I used a Lakewood joint, because that's the only thing that I knew would work. But, the Lakewood is too expensive. And, they don't make joints anyhow. If you buy a Lakewood, it was made by one of the big U-joint makers.

I bought a GMB joint for my '68 Bird, because it was the cheapest conversion joint I could find, at the time. From the info I could find, they're made in Japan. And, since the quality of Japanese vehicles seems to be better than some USA vehicles, I assume the GMB joint would be just fine. Some say that Spicer joints are the best. But, online info says that they're now made in Mexico & their quality is not what it was. So, a Precision/Moog or Neepco is probably just as good.

The Neapco number is 3-3130. So, I assume this Duralast joint is is the Neapco joint, in a DL box. It's the cheapest conversion joint I can find, so far.

Here's the GMB I bought.

The Moog/Precision number is 372. if you buy from Rock Auto, they have the cheapest price I can find, if you can add it to some other stuff you're ordering anyhow.

https://www.rockauto.com/en/parts/moog/precision,372,universal+joint,2392

Here's one for $18 shipped.

They're $19-$20 on Amazon.

If you don't have a slip yoke, you can either buy one from a fellow Pontiac guy, or buy a new one. They're less than $45 on Ebay. If you buy the PST shaft, with 1310 joints, you can order a slip yoke that uses the 1310 joint & won't have to buy another joint, for the front. Don't know what trans you have. But, if it is a TH350, you'll need the small slip yoke. The PST # is 100001.

If you discover that you actually need a 48 1/2" shaft, you can order a PST shaft, which is 48 5/8" long. These have end yokes for the larger 1330 series joints. I needed a 47 1/2" size for my current '80 bracket Bird project. So I bought one of these, in a 47 5/8"length.

It's $150, shipped from an Ebay seller. The 48 5/8" length is part #300515. The 47 5/8" length is #300505.

https://www.ebay.com/itm/Precision-Shaft-Technologies-300515-48-5-8-Long-3-O-D-Steel-H-R-Drive-Shaft/143002704747?hash=item214ba01b6b:g:P1AAAOSwZFxb4LC0:rk:1:pf:1&frcectupt=true

If you go with this shaft, you'll obviously need different conversion joints for both ends. They come without any joints. So, if you have the 1344/S44/3R joint slip & pinion yokes, you'll need a 1330/1344 conversion joint.

They're $12.50 on Ebay.

The Precision/Moog number is 355. They're $14.59 on Amazon.

https://www.rockauto.com/en/parts/moog/precision,355,universal+joint,2392

https://www.summitracing.com/parts/mog-355

The way I measured for mine was to push the slip yoke all the way into the trans as far as it would go. I then measured from the the center of the slip yoke U-joint hole to the center of the pinion yoke U-joint hole, then subtracted 3/4", to allow for aprox 3/4" slip distance. It came out real close to 47 1/2", so I ordered the 47 5/8" shaft. It worked out just right. I have almost exactly 3/4" slip.

My car is an '80 Bird, with a 455 & short tail TH400 trans, and a stock 8.5" 10-bolt rear end.
