How do I know what size ujoint I have (1310, 1330 or 1350 series)?
The series is determined by two measurements, the end cap diameter and the width of the ujoint. First, measure the ujoint end cap diameter, if it is 1 1/16" or 1 1/8" then you have either a 1310 or 1330 series. Because each one of these two can have either cap diameter or a combination of the both on a ujoint, you must measure the width of the ujoint to determine which series it is. Measure the width with the caps on, if you come up with 3 7/32" (just under 3 1/4"), you have a 1310 series and if you get 3 5/8", you have a 1330 series.

If you measured an end cap diameter of 1 3/16", then you have a 1350 series ujoint and the width will ALWAYS be 3 5/8".

do you have a S&W Race cars catalog?
if you do or can get one there is a detailed drawing with dimensions and specs in there.
you can probably also find the info online here by searching some of the driveline companys.

While you guys are on the subject... Anyone ever encounter a rubbing noise at the front yoke when you go over a bump. I have a muncie with 1350 yoke and a jegs cross member. I'm using a after market mount that seems to be higher than stock but really don't have a stock mount to measure against. Stock trans tunnel. This is a new build and still killing bugs. Thanks, Rob.
