1990 - Rear Wheel Hub Assembly Interchange

1990 - Rear Wheel Hub Assembly Interchange
I am going to visit my favorite JY to look for rear hub assemblies for my 1990 XJ40. The lugs keep stripping at 75 ft/lbs. I have already replaced 4 lugs on one wheel and upon tightening the 5th (old) one spun.
My plan is to get a used set of hubs and replace all of the studs at a machine shop using the splined type lugs as used in the front hubs. My machine shop says they can do it.
Does anyone know what year model hubs are a direct fit on the 1990?
If available at the JY, I would want to pull the Hub and Hub carrier assembly as a complete unit.
Thank you.

@Robman25: I am talking about the rear hub. As you may be aware the rear lugs are threaded in and peened from the back side. I want to replace the screwed in lugs for the splined type on the rear. Did you use your method on the rear hub?
I have used your method to replace the front lugs, but the rear??

I don't know if this would be practical, but if the problem is that the lugs are stripped and rotating in the hub but the lug-thread-to-wheel-nut is OK, what about introducing a small "keyway" between the lug and the hub? Drilling beside/partially into the lug and inserting a steel pin dipped in JB weld?
Just a crazy idea but one I would try!!
all the best

Just to be clear. I installed 4 new lugs ( that's the number I had in hand) and had all 5 lugs spot welded on the back side. The 5th (old) lug did not strip out in the hub. The old lug nut itself would not tighten. I replaced the old lug nut with a new lug nut one from Welshent and the same thing is happening. The lug threads on the wheel side is stripped.
Now the new lug nut would not unscrew. It just spins on the lug.
On another note, I received faulty axle nuts. they would not thread on to the axle.
On the first (threading with a ratchet) one the the helicoil jammed on the axle and the nut unthreaded from the helicoil. On removal the helicoil unwound itself. On the second, the nut just unthreaded itself from the helicoil. The helicoil will not thread back into the nut. Welshent will replace nuts.

Awaiting new axle nuts. I did clean the threads with a wire brush prior to the attempt to install the new ones. With that lesson learnt, I will be careful with the installation when the new ones arrive.
BTW: In the interim, I installed the old axle nuts with red loctite and torqued them to 200 ft/lbs. This was done so I could test drive the car.
Is this good? I was told that this is a no no.
