A little more progress.
Side mirrors were made out of 1,5mm plastic and 0,5mm soldering wire
Mirror brackets are little complicated, then Big trucks have. PickUp doors have a slope at the top point.
So I improved my old soldering device.
The wire was localy flatten and drilled for rivets. Here I broken one of my 0,4 drill bits.
I have got Cab roof Marker Lights from Fireball Modelworks. Thank you Joseph!
But as Joseph said: "they are smallewr then Silverado's one. Compare to photo 4.
I plan to use rectangular black adhesive tape as a rubber for marker lights. Visually it should make them larger.
Note, that wipers were cut off.
Finally I made cab handles from square styrene 1х1мм & strip 1х0,3мм.
