Finished my full width swap and Have a ford 9in from a bronco in the rear. It has a 1330 style ujoint. My t case has a mega short sye with what every style it comes with. I planed on taking a front Cherokee shaft and getting it lengthened which is fine but will cost $200.

I read that it is cheaper to shorten a shaft rather than lengthen it. If that is e case I have the factory bronco shaft which is 8in longer than I need and it will fit the ford 9in. Only problem with that is it will not fit the t case.

So do they make a conversion cv joint that with mate the bronco shaft to the np231?

Another plus of doing this would be the bronco shaft is 1" thicker

 

Yes they make a 1330/1310 joint. 231 will have a 1310 yoke so it should work no problem.
