Looks like you have a pair of deep dish (Ranger) fronts & a pair of regular (Pajero wheelie/Brat fronts

I can't help with parts, but AFAIK the rears are unchanged across all fitments so any would be correct - and re-re Brat rear will probably be the easiest to find

Nice chassis tub BTW - most have had the front body mount fitting broken off, and/or been butchered to take a stick pack  

Sorry Flo, I can’t help with those wheels.
But I’m looking forward to see this restoration come along.

Jonny, the front body post is brocken but nicely. So I would be able to repare it. The rims are unfindable on ebay. I will ask to tony. Wich rims were on the pajero? Ranger or brat? 
I will try the peroxyd method tomorrow the tey to whitening the parts.
Thaks for your advices guys.

The chassis has been cuted on the rear bath maybe for a stick

First bath of my life with peroxyd. I followed your advices and have the luck with a shiny weather. How long do I wait? 

I’ve only tried this once, but I think I left mine outside for about 7 or 8 hours.

Thank you Al. 

If you have a uv light you can use that but also use metal foil to reflect the uv I have seen it done with old motorcycle parts.

Working on rc under the sun is always a pleasure.
after a good bath with liquid+dish soap (1night) and a little white spirit, all parts was clean. And the rebuilt so easy as the lunchy.
Diff is different to the grasshopper to. It is reinforced underside. 
And here is the result. I had the front body posts for the body.
