Good looking build! Paint looks super.
I had an issue with decals on tires also. I now scuff and paint with acrylic paint then apply decals with setting solution, after some satin clear.
Actually yes, the two I got, 66 Bonneville, 66 Mustang Fastback, 51 Chevy, 68 Dodge, 53 Ford Truck, ElCamino, 32 Vicky, Opel, 78 Bronco and more Price want from $19.95 to $24.95
I am dealing with one of these also. A lot of test fitting! It goes in and out of the box for me to get a breather.
Although challenging you did a good job on it! You can always ad shocks, but personally I wouldn't be concerned, heck, half my builds are missing driveshafts!
