Hot Rods More U -joint questions

After not being able to source a u-joint to go from a stock 55 Ford driveshaft to an FMX yoke, i've decided to go ahead and swap out the rear end. Can I get a u-joint to adapt the FMX to an S-10 driveshaft/rear end combo? Or what rear end and parts will work to get me back on the road??

 

You could have your driveshaft modified. Weld on the end that you need to match the FMX yokr and have off the shelf u joints.

Most large truck shops offer driveshaft services and balancing.

 

what ujoint does the FMX yoke use? and are there different yokes available to fit that transmission?

The S-10 might use a very common (in both fords and chevys) 1310 series ujoint.

 

Just swap out the end of the drive shaft?

 

Reason I wanted to change out the rear end is because of the steep gears in the stocker. As long as I cant find a u-joint to fit it.

 

first place to start planning it out, is to figure out what U joint the front yoke takes. Start by measuring the dimensions exactly, the diameter of the cups, and the distance between the snap rings, which is usually the overall length of the ujoint. here are some common ones, the 1310 was used in lots of GM and Fords, the 1330 was used in Fords mostly in the 70s. There are many other sizes, of course.

 

There is a Car Quest u-joint catalog online (link below). Everything you wanted to know about them and more. Most likely the 'shaft and yoke are 1310 series. But look at what Jim posted above, good information. There are combination u-joints and most likely you'll be able to find one. The catalog also has a cross reference to Neapco and ****er products.

You know where the drive shaft came from. If you know where the FMX yoke came from, it will help you in the selection process.

I needed a 'shaft for my Ford, considered a junkyard one and I'd have to find 'joints for it. I opted for having a 3.5" one made up with all ****er and Neapco components for a flat $300.

Like always the good stuff is in the back of the catalog. When i worked there, the Carquest joints were made by Neapco.

Good link. Thanks

 

I saved it as a PDF file, a pretty good reference. I learned a few things I didn't know. Lakewood & Mr. Gasket were the only source of odd 'joints when I was racing stock cars. Or so I thought.
