: axle yolk question

the 8.5" axle that i just installed in my 67 came out of a 73 nova. of course my driveshaft is too long :( I will measure it today but it seems like 1.5" too long.
my question is when i have it shortened i want to have them change the yolk as the one i have now does not fit anyway. is this called a 3R type?
i have read here that i can use some conversion u-joint to make it fit. I would think changing the yolk would be stronger. what it the popular opinion?

thanks

I am installing a 8.5 from a 73 nova in my 68. I agree it is too long but are you sure about the U Joint?

There's a pic of my 3R yoke in this thread: http://www.camaros.net/forums/showthread.php?t=93677&highlight=1310

The OE Camaro driveshaft uses a 1310 U-joint. The 3R is stronger. You can get (or the driveshaft shop can get) a 1310-3R hybrid U-joint. The Spicer number for this joint with a grease zerk is 5-3022x . Solids (non-greasable) are stronger, but I do not have a part number.

Some info on relative strengths I found on-line:

1310 Spicer Series: 1 1/16" Cup Diameter (Dim C - Diagram A) 3 7/32" length (Dim B - Diagram A) Certain Ford applications have 2 cups 1 1/8 Diameter. Appropriate horse power range is up to 600 in circle track or road raceing, small tire drag racing and 4x4.

1330 Spicer Series: 1 1/16" Cup Diameter (Dim C - Diagram A) 3 5/8" length (Dim B - Diagram A) Certain Ford applications have 2 cups 1 1/8 Diameter. Slightly stronger than 1310, Used in 5.0 Mustangs

3R Saginaw Series: 1 1/8" Cup Diameter (Dim C - Diagram A) Retained with internal clip 2 5/8" (Dim B - Diagram A). Most common GM joint. Horse power range up to 700 in road racing and circle track. Solid drag racing U-Joint can accomodate most sportsman classes.

1350 Spicer Series: 1 3/16" Cup Diameter (Dim C - Diagram A) 3 5/8" length (Dim B - Diagram A). Best choice in Drag Racing. can manage over 1200 horse power in drag racing applications.


Since my TKO uses a Ford 1330 slip yoke, I had my driveshaft made with a 1330/3R solid in the rear.

The '73 should have had the 1310 yoke. If it has the 3R then someone swapped it or it isn't a '73. The 3R wasn't used until '76.

man, a picture is worth a thousand words. you guys are right, it is the 1310. now that i can see a pic of the different types it is clear. :D

thanks everyone. :thumbsup:

my joint still does not fit into the yolk but i see now that someone had boggered up the yolk a little. i will hit it with a file and it should fit. so i will just need to shorten the shaft 1". NAPA is going to send it off on monday i hope. here is what i have.

Yup, that's a 1310. I am surprised you need to shorten, but I guess you have a non-OE tranny? Do I recall you have a 200 4R?

no, not a 2004r yet. still a th350. hoping to switch soon. the car was a 6 banger/ 3 on the tree from the factory. not sure if that had anything to do with it or not. i can just about get the driveshaft in place but it is shoved into the tranny tight.
