What Ujoint

[1973dusterkid]

Ok so my set up is 73 duster 4 speed with 83/4 diff just swap gears and ended up using a 489 case I did have a 741 case now it’s all back in the car I know the ujoints/Yoke is different the 489 uses a larger ujoint but what ujoint does it use

Most likely 7290.

Measure and look them up in this chart.

Dennys Driveshafts Dodge Plymouth Chrysler universal joints for your Mopar performance street car or truck muscle car or race car U-joints in 7260, 7290, 1330, 1350, 1355 AAM, 1410, 1415 AAM, 1480, 1485 AAM and 5380 series

good luck

You probably have a 7260 driveshaft, and a 7290 pinion yoke. There are 7260 yokes for 10 spline 2881489 pinions, And there are fine-spline 7260 yokes for the big pinions, but last time I checked they were over $150, and that's a long long time ago.
Oh Geewhiz already covered in previous post, sorry

You can get an combination U-joint....listed as 2-0527. It's not the same number I used ( a Precision U-joint), But I don't remember the Precision# either.

let me offer one more alternative. We have a really good 4X4 truck place in Topeka that also specializes on drive shafts. If you take accurate measurements on the diff yolk, and take in the drive shaft, they will install the correct U-joint for a very reasonable fee. I think the last time I did it they charged $40 for the part and installation. And it was a good quality part. That way there is no guessing. See if you have a similar place.

I think I’m just going I take him a yoke and driveshaft and have my driveline guy set it up
