U-joints
 

I was wondering what U joint came on a stock thirdgen driveshaft? Is it 1310/1330/1344 and I know its not 1350.

Anyone know? I want to order the conversion U-joint soon.

pretty sure they were 1344

Great now I've gotten 2 diffrent answers! lol

call an auto parts store

Well I looked on summit and they only show 1344 and 1350 so I tink you might be right.

I am 99% sure it isn't a 1350

I am 100% sure lol

I am pretty sure my stock ls1 was a 1310 and when i got the 12 bolt they gave me a 1310/1350 to mate it up.

Looks like I might just bring my shaft to a place and have em match a 1350/xxxx to it and put my new yoke on.
