They call it a urban crossover, the CMP platform was designed more with this type of bigger car in mind unlike the former PF1. The gearbox has technically 2 or was it 3 clutches but in any case isn't a "classical" dual clutch gearbox. One thing to keep in mind is that customers really, really like the look of those SUV/Crossovers so manufacturers can get away with cheaper materials for the interior and many other things that wouldn't fly on a bland sedan of similar price.

So you ended up with a Peugeot, it must be fate

The BA10 wasn't particulary suited for a big Jeep going off road, the 224 lb⋅ft from the 4.0 L6 didn't help either. Instead of a V6 you could try the AMC 4.0 L6 or even the AMC V8, the AMC bellhousing is very cheap unlike the GM one.

That is indeed not good, you can find solid ones made out of aluminium in Britain. It seems the original type is NLA but some vendors still have a few in stock: https://abmecasport.fr/shop/mecanique/courroies/poulies-damper/poulie-damper-309-gti16-405-mi16-1-9l https://lechticomptoir.fr/1856539-Poulie-damper-Peugeot-405-Mi16 The part number is 0515.E9 bdw.

If the hex heads are 10mm the 5 could be machined down to 3/8", but with 21 good ones why bother. Is the Swiss cheese nut hard to find?

You can try to ask the manufacturer from 2012, they do custom cables for old cars: http://www.mauricelecoy.fr/range-of-products.php

In a pinch you can make small rods yourself with ball sockets and threaded rods but you must use sockets with a safety clip. The price is nearly the same but it won't pop that easily. The downside is that you have metal to metal contact unlike with the OEM rod.

For anything that isn't a PRV you need another bellhousing. Jeep had a 4.0 L6 bellhousing that should also fit the AMC V8. If you can't find a ZN3J or a Volvo B280 try to get your hands on a 3.0 Eagle Premier engine.

I just found out that the V6 existed with and without ABS so maybe they had the regular LSD and not the Torsen.

A 505 with ABS should use a Torsen diff, that's why Peugeot had to stop using the cone type LSD for the Turbo and V6.

I did buy an "original Peugeot quality" dipstick that was inside an unsealed PSA packaging with the end of the printed part number strategically damaged. Good thing the barcode under it was still fine and read 1174.49 instead of 1172.99.

It's a 5 year old post but if anyone need a Mi16 dipstick just get yourself a TU engine one part number 1174.49 and mod it. You have to shorten it and cut a new notch for the max level, min level (former TU max level) isn't exactly as low as original but it's not a bad thing on a XU9J4.

The good thing about the US models is that you can find brand new sealed beams to fit inside, even modern LED ones. That can be usefull “just in case” now that euro H4/H1 headlights are hard to find.

The 505 Sri in Argentina had some but you need to find the center plate, the original are smoked but the manufacturer (Fitam) also made clear ones: http://www.farosfitam.com.ar/productos.php?l=4&m=114 Argentina also had some type 2 smoked aftermarket ones, no need for the special center plate but they are even harder to find: https://articulo.mercadolibre.com.ar/MLA-636217756-lente-trasero-peugeot-505-gamma-fume-8791-_JM
