Hi Raffael,
This model Volvo was an unknown to me, so did a quick search on the internet ... supposed to have a 12 liter engine! WOW. Learned something new.
I also thought the frontgril looked a bit weird but turns out you got it spot on!
Found a period pic of your truck (or close to it) on
pinterest.com
Thanks for showing your build. Do you have any more info/pictures on how you made the cabin and for that matter the frame of the truck.
Cheers!
Stephan
