CAT XLS revival - help please

[Npdp72]

Hi,
I am finally getting round to rebuilding my old CAT XLS from a bag of bits.
I used to race this around 25 years ago, then moved onto a ProCat.
I think the XLS is about 70% complete, some bits have gone astray or been used on my ProCat years ago.

I'm sure as I go through the build many bits will be required, but for now there are a few obvious bits I need without which I won't get very far, these are:
Rear trans housings T070 & T071
Front suspension brackets T056 & T057
Upper rear suspension mount (plastic bit) T079
Bumper & Wheels

If anyone can help, I would be very greatful.
I may also have some useful parts to sell / trade in my bag of bits.

Finally, which of the reproduction body shells and undertrays are the best in terms of quality and reproduction of original shape, fit and detail?

Many thanks in advance for anyone who can help,
Nigel
