You might already the two stud plates in the floorboard that the U-brackets bolt to. If so, you just need to weld a couple tabs to the trailing arms to accept the end links.
Here are some pics. I'll try to find others

Not sure what you mean by "differential support mount"

Here's a good pic of the rear arms with the little brackets on the small end

As Doug said, the bar was fixed to the body above the diff/prop shaft, on the sloping bit of the body in front of the rear axle, by two brackets just like the front ones, that were fitted to studs protruding from this part of the body, with rubber bushes round the bar. The bar had a right angle backwards at each side the end of which bolted to the radius arm as shown in Doug's link photo.
FWIW, I believe the V12 handles much better without the rear bars, providing that the rear ride height is not too high and providing that the rear wheels have 1/2 to 3/4 of a degree of negative camber (adjusted by removing shims from the inboard driveshaft to diff coupling flanges). On my car this combination gave very progressive break away characteristics and very responsive adjustment to steering and power inputs.

Many agree.
I prefer the flatter stance so the rear bar was good for me. I'll say from experience though that a too-big rear bar is definately a bad thing on an XJS.....unless you *enjoy* very sudden breakaway at the limit!
I found that if a 4000 pound Jag gets away from me it's very hard to reel it back in :-)
After experimenting with different bars, if I had to do it all over again, I stick with the smaller standard bar...which was only 9/16th inch as I recall. You'll still get much flatter cornering and less understeer...but the car will remain predictable.

This thread is the best I've found so far with regards to pictures (via the Jag-Lovers link) on where the Rear ARB (Sway) Bar Brackets should be located. That said I'd really appreciate it if anyone either the original fit or an aftermarket fit Rear ARB fitted to their XJS/6/12, if they could post up some more pictures and or dimensions of the brackets in relation to the chassis.
Yo very much appreciated!

I wouldn't be surprised of the mounting holes are already there. My 94 V12 came from the factory with a rear bar. The rear ARB seemed to be an on and off again thing, depending on market and year. All the parts except the bar itself are available from Jaguar. https://www.jaguarclassicparts.com/u...bar-sportspack

The radius arms, for the XJS at least, can be bought with or without the fixings for the ARB droplinks.

Unlike the XJS, a rear bar was never intended for the Series I-II-III sedans so Jaguar never bothered to pre-install any of the hardware.
If opportunity permits in the next few days I'll take some location measurements from my installation.....which, frankly, wasn't the least bit scientific. I did a mock-up and drilled holes for the U-brackets taking into consideration where the surface of the floor pan was flattest, clearance for the ends of the bar, and other things which I've forgotten at the moment.

These pictures are not great, but show the location I used on a S1

Jaguar itself apparently had difficulty deciding if the rear bar was worthwhile. All the pre-HE cars had one. After the HE was introduced the engineers (or accountants?) were very selective about using 'em.
