Well . . . at least you have a good start. Building your 'Frankenstein' by starting with the heart, lungs & spine is a good plan!
The T in my head, thoughts?

Thanks for showing how you measured for the belt. I would never of thought of using my wife tape and she has many to choose from. Even an old guy like me can learn something new. I think I'll sneak one out of the house and put it in the garage for future use. Keep posting picks like what I see so far.

I can try to help but no expert so others may want to chime in.
Jag rear ends came in 3 widths over the years (approx. 53", 55" and 61.75"). Yours is likely XJ6 Sedan type at 61.75" with half shafts horizontal. 55" considered the most desirable but XJ6 can be used, as is, half shafts and lower control arms interchanged, or even narrowed. Mine is XJ6 narrowed to 57"
2 types of XJ6 rears, Salisbury and Dana. Salisbury has round pinion flange, non flat body and drain plug. Dana has flat bottom, no drain plug and square flange. Yours appears to have round flange so likely Salisbury.
Ratio should be on one of two tags under rear end cover bolts. Ratio is given either as a number or the teeth numbers on pinion and crown wheel like 19/70 is 19 divided by 70 or 3.33 to 1.
You can check for BPL (British Posi Lock) by holding one wheel and spinning the other. BPL will try to spin the held wheel in the same direction. Otherwise, non posi.

Found the tooth count ID tag
Also verified by turning pinion and counting, it is indeed a 3.31:1 ratio open diff. I'm not disappointed by the open diff, one would think it makes life easier with a huge rear tire, skinny front tire and minimal vehicle weight
I was also pleasantly surprised to see that my BMW 5x120mm wheels bolt down to the 5x4.75 jag hubs enough to have a set of rollers while working on the car. I have two sets of BMW wheels, they are not a mainstay.

Good call. "snow ploughing" is not fun.
Make sure all is well with the diff. They are EXPENSIVE to rebuild.
