Hello
Blubaja, I've understood that I must put accessories in the ceiling, correct? if it is thus, I do not agree with you... is a race car, not one of quickly assistance, reason why the ceiling will go without no type of accessory or roof rack
About the rims and tyres, look this:
The tires go fixed to those styrene pieces, since the tires are a little greater than the rims, but when he is everything painted as soon as it will be appraised
Bigfrit, very thanks for your reply

Now I will advance the Unimog, that have come to me today, and with the HDJ interior. I need to have ready both vehicles to paint and to place the decals at the same time. I will put new post to you with the Unimog...
See you!
