Np203 front output
 

New to this forum. Not sure if you guys deal with the older blazers or not but I guess I'll soon find out.

I have a 73 with a np203 transfer case. The chain started slipping really bad so instead of rebuilding I bought a used one off of craigslist. The old case had a 10 spline "yoke style" front output. The new case has a 30 spline "square flange" front output.
I would like to keep my current drive shaft since it is new and wasn't cheap. I can't seem to find a flange style shaft that is short enough anyway, and I don't want to fork over the $$$ for a custom.
So does anyone know if a 30 spline yoke style output was ever made? Where I can order one, or what vehicles I should be searching the junk yards for?
Thanks

You should be able to find a 30 spline 1310 yoke that would allow you to use your stock driveshaft. From my searches, the spicer PN is 2-4-4801 which is an obsolete part from Dana, but still looks like it is available from a number of online retailers.

Thanks, that's the one I need.
