Yes a lot of changes, the original springs were badly sagging and I replaced them with a set that were too high but that was all that was available back then. Getting parts for Mk2's and S Types was not the easiest thing, the Jaguar main dealers had nothing for them so the only outlets beside breakers were the independents, the two in London being Normans in West Hampstead and the other Nolans in South London, I had to wangle jobs in the truck to get to visit them. The rear springs I found in a local hot rod shop that were on display as an advert for a local chroming company, they told me they were for a 420G and sold them to me for next to nothing. They remained on the car for the next thirty years, thanks to Watjag they have all been replaced. In 1986 after the new sills and floor pans were fitted at the Shoreditch workshop I resprayed it BRG and swapped out the auto box for the manual OD box in a rented workshop at the local marina. The round wheel arches were made in 1977 as the wings had rotted out and repair panels weren't available and new wings if you find them would have cost far more than the car was worth so it was better than nothing, don't forget these cars were old bangers and practically worthless back then, I had scrapped a couple of Mk2's I bought for £20 each and one other S Type that cost £100. Fortunately door's were readily available from breakers yards for about £8 each. Ten years later in 1986 I bought the S1 XJ6 for £650 that I've just sold this month and that was expensive for the time.

The worst towing of the S Type was being pulled on a twenty mile drag from my old garage in North London to Hertfordshire behind my friends Morris Minor van in the pouring rain and no servo brakes. This was no ordinary van though, it had a radical roof chop and a Ford V8. When he accelerated the whole van would distort, not sure it was the best construction job in the world!
A lot of changes to your S type since then Nigel. I see round wheel arches and the red paint. The front is riding very high as well. Is that the tyres or did you not have the engine in?

In the UK we also have a thing called a "towing bar" which is basically a straight metal tube which attaches to the rear tow bar on the car and to a towing eye on the car being towed and is a lot safer than a length of tow rope as we call it in the UK or as you know it a "Lasso".
So many changes made to our English language made by foreigners. LOL.
Still more terminology differences. Here in the USA a towing dolly is this two wheeled device use to tow a car. Often used with front wheel drive cars to keep the drive axles from turning. Here is how I moved my MGTD 540 miles from California to Oregon some 12 years ago. The Morris tow bar was not compatible with the MG.

Different continent, different terminology for the term tow bar. In the USA what connects these two cars is a tow bar

It would be better to secure to the chassis rails but this was all you could get back in the seventies when I fitted it. I had to make a new rear valance the cross bar is fitted to as the panel was unobtainable so took the opportunity to reinforce the whole of the rear of the boot area with 3/8" steel bars welded in place behind the valance as well as the tubes for the fixing bolt's. The base of the wheel well inside is further reinforced with extra steel to spread the load. I used to tow the caravan fully loaded with all the stock and trappings of a trade stand to car shows all over the country and towed a few cars with no problems. I've never tried a car trailer on the back as unfortunately I've never had access to one but I don't think it would be a problem, I'd be more concerned for the clutch.

A firm that supplies a large range of towing hardware might be worth a call is GT towing at Potters Bar Hertfordshire, they have been around a very long time and used to supply bars for the S Type back in the day for our cars. I'm not sure if Watling towing near St Albans are still going as the last time I went there the yard was all shut up.

Modern tow bars are generally attached securely to the chassis legs but yours Nigel is basically bolted to the relatively thin metal of the floor. Probably good for towing small light weight trailers but I would not want to tow another car on a trailer or a large caravan with this attachment. It would put a lot of stress on the boot floor even with mounting plates.

I have a tow bar I fitted to my car many years ago to pull a small caravan. Not sure what make it is as I found it at spares day for a tenner, I think it's part XJ6 and part S Type, I had the fittings that go through the bumper but didn't fancy drilling holes in it so it has an angled cross bar bolted to the rear valance. This was reinforced with thick wall steel tubes welded between the outer valance and the boot rear side. The under frame is bolted to the boot floor.

The article on towbars in Newsletter Vol. 5, No. 3 gives most all the information available on the Witter towbar that was made specifically for the ‘S’-type
An update: I finally (after having it for 50+ years) installed a Witter towbar on P1B79909DN. I built a trailer for our 1928 BSA (which was a 40-year restoration!) to take it to British car and bike shows. The photos show the hitch on the car, with and without the spun aluminium ball cover. I installed it with just the two ⅝ in. bolts, pads and spacers though the bumper and rear body structure as the bike and trailer weigh only about 400 lbs and the tongue weight is 30 lbs.
For heavy loads, with high tongue weights, the vertical plate and centre bracing bar would be required to keep the bumper from twisting and distribute the load into body.
