Yes Brad those are the part numbers if your going to use the 1410 series u joints. Later 427 cars use these. I am building a 289 based car. They used 1350 series half shafts. To use the bigger series half shafts in a 289 car you have to hog the rear spring tower side plates out. There is no room for the bigger stuff to go thru the side plates. I want mine to be like they were originally.

Your problem on the jag rear comes from the fact that you are not using the inboard brakes that they came with. You need to make a ring with the right bolt pattern and center bore size . Your half shafts will then mount like they should.

By the way I have all the spicer parts you list minus the male slide yoke. I will not have a use for these. I would give someone a good deal on these!
