I don't know about 1310 or 1350 seals for Dodge. But, the seal for a 1410 fixed yoke for a NP241D is one of the following.
Napa #21061
Or
National Seal #473204 (Advance Auto)
These numbers came up in a RCC post many years ago and I kept this information for the day I installed 1410 yokes, ujoints, and rear driveshaft. I haven't done it yet.
Also, Jeep used the 1310 ujoints and yokes in their 80 thru 88 J10 and 80 thru 83 full size Cherokee from behind their NP208J. Those seals may fit the Dodge NP208. The same seals may have been used on their NP219, NP228, and NP229. But, I don't know that for sure. And, I don't know what the output shaft spline count is for the 1310 yoke. But, it may be worth cross referencing those items.
EDIT: Just looked up notes on my old J10 Build. The Jeep NP208 1310 yoke is also 32 spline and uses the Autozone #473204 seal. That should also be available at the other parts stores.
