More than likely 1350, but here is a link to the measurements.

The U joint is going to have to be matched to the yoke and driveshaft you use. If you have the yoke you can figure out what it takes by taking a couple of measurements and comparing them to a u joint size chart.

Note: the chart USMCChevy gave seems a lot easier to use than the one I gave below.

This site gives you the dimensions and parts numbers for Spicer U joints. Get the Spicer number and you can cross it at any parts house but the Spicer brand U joints are worth hunting down. http://www.mdsdriveshaft.com/spicer_...sal_joints.htm

You also need to know if your yoke and driveshaft have inside or outside snap rings. Preferably both pieces will have matching snap rings or it takes an extra cost U joint most of the time.

Different sizes for different years, one or 2 piece shafts, car or truck., slip yoke or bolt on yoke. Which 400 are you asking about? Could be either 1310 1330 or 1350.

All are 1350 that I have dealt with

Thanks, i got me a new 1350 slip yoke for the trans and a good 1350 drive shaft and new precission u-joints. Now its time to decide on what rear axle i,am gonna run. Sstock 12 bolt, 9" ford or dana 60. Leanning towards the 60 as i have a power lok for it.
