NP203 rear yoke - 1350?

[pismorat]

Do they make an output yoke for an NP203 that will accept a 1350 u-joint? I just blew up my 1310 and took out some other pieces under the truck and don't want to do it again. I have enough spare parts to rebuild it stock, but I'd rather upgrade it if I can.

203 and 205 use same yoke. find a 3/4 or 1 ton rear yoke should be 1350.

Dang it, the truck I got my 489 BBC (the u-joint buster) out of was a 3/4 ton truck and it had an NP203 with 1310 in it. I think it was a 2wd converted to a 4wd, so that'd make sense. Are the 1350 yokes only on 3/4 or 1 ton NP205's, not 203's?

i have a 77 k30 was factory 2wd or somthin . on the assembly line thay made it 4wd. got 3" block rear with bump stop ear's to hit the frame bumpers. then 2 peice shaft was 1310 at 203 then jumped to 1350 the next 2 and had carrier bearing.

that was a short 10-12" shaft for the first part .

Has anyone else had experience with this...I need to know where to get a rear yoke and whatever else might be needed besides modifying the driveshaft.
