Looking for a U Joint

[anlauto]

Okay I have two small block 1970 Barracuda's on the go, both have drive shafts with a small U joint up front (7260) and a large U joint at the rear (7290)...The large U joint is no problem....but I'll be dammed if I can find the right front U joint


I've purchased three different MOOG U joints now, all supposed to fit but they are all 1/8" too wide  What gives ?

Any body find a brand that will fit ?

Spicer U-joints are the best AFIAK. I bet they'll make one. They have an online catalog. NAPA sells them.

Dana Spicer 5-3228X

That one says "The span between the yoke inner surfaces where the "C" Clips lock in is 2.125 inches"  which is the exact same thing ALL the Moog ones I ordered say ......My yoke is 2.125 or 2 1/8" ....

HOWEVER every U joint I've bought is NOT 2.125  but in fact 2.250  1/8" too wide 

I was hoping someone else has had this issue and found a solution with a different brand....I don't want to keep ordering U joints, they're starting to stack up...

Got a pic of the yoke, sounds like that's the problem, compressed maybe?

NO...the problem is NOT in the slip yoke or the drive shaft. I have both original U Joints Detroit 2266909. Look at the measurement on the original joint compared to the new joint. The new one is 1/8" wider. I didn't adjust the caliper, you can see the difference.

I use these guys in missaugga often.  http://www.patsdriveline.com/ - give them a call and the dimensions they should be able to get you the right ones

Alan,

I had the exact same problem a couple of weeks ago when I installed my drive shaft.  2 New joints, Spicer?, at NAPA, got home and they were two large.  I'm pretty sure I ended up with these:

They swapped me out, no problem.  On the spicers - the information in the parts book was just wrong.

I'm going to NAPA tomorrow...hopefully they will have one in stock  so I can measure before buying.

Alan - i just went through the same thing.  I ended up buying a Duralast u-joint (1-6301DL) from AutoZone for the front.  it fit fine. The Spicer 5-789X is supposed to fit but doesn't.

I saw the title of this thread and thought "Alan, go to your local cannabis store. They have a joint for U." 

[anlauto]

Went to NAPA this morning....and ordered the UJ246 as mentioned above. dimensions say it measures 2 1/8" but take it out of the box and like all the MOOG joints I have here it measure's 2 1/4"    My local CARQUEST no longer carries "CARQUEST" brand, say they are all Moog now. The carquest 210-1306 as listed above crosses over to the 246 Moog which is again too wide....

Back to the start again...

Alan,
Try and find a NOS Chrysler one.

Hey Alan, If you put the caps on the u-joint, and put c-clips in the grooves, yours measure 2.250 outside to outside on the c-clips???

The newer u-joint centers are beefier in strength, so I can understand your measurement, but it's the cut of the groove on the cap that determines the 2.125 outside to outside of both grooves. New caps could be 1/16 shorter than the old ones and still have grooves in right place on new centers.
