NP205 Rear Seal

Does anybody know the part number for a NP205 Rear Slip Yoke seal like the one shown below? I'm trying to fix all the leaks on my truck but finding seal part numbers is a pain.

Re: NP205 Rear Seal

look it up for a 1980's std cab long bed k30 . they got a lot of slip yoke 205's in them .

looks like rockauto shows a skf 18992 for the rear seal on a np208 and 205 since there both slip yoke on the rear . and the 205 info said if 131.5 w.b. spec = std cab long bed .

and fyi check and make sure the bearing in the tail housing looks o.k. its just behind the seal . the slip yoke rides on it .
