Ok, time for a update on my build. Slow progress as I said, since I'm trying to finish another build before the end of the month.
A lot of filling and sanding was required where the final drive housing meets the hull. There was a "Hotchkiss" moulding on the hull, but the sides were kinda square with rounded corners, which is incorrect according to the vehicle in Saumur. Eduard provided the answer
The drive sprockets position is too far forward, but I decided to ease my pains and leave them there. They are hollow though, and looked like , so I decided to make a custom fit styrene washer with the help of my trusty Dremel. They do not rotate BTW, only the roadwheels do.
The roadwheels assembly was a pain to clean and put together. I actually broke one of the outside part in 2, easy to fix though and the break is hidden by the axle. Extreme care has to be taken when gluing the assembly to the hull, as the alignment is horrific. I temporary installed the idler wheel, then glued the center assembly, making sure with the track that everything was aligned. The others were easier this way.
Some interior parts are provided. I did not glued them in place yet, and they are not fully completed. Still need to do some PE and plumbing.
There is a gap on the left side between the transfer case and the hull. I will shime it later.
As you can see, the alignment for the drive shaft is just out. I'm still thinking of a way how to fix it.
I also dry fitted the tracks, they are way too long. Still better than too short though
