My Hunnicut book shows the M-4A3E8 (105) with the HVSS,so I decided to go smoke free,and just make it go
BANG!

I used hex styrene rod in predrilled holes,to simulate the bolts attaching the suspension mounts to the hull.

I will add the support rollers after the painting is mostly done,I have masked off the areas where I will glue,to avoid having to scrape paint.

This is a simulation of hinges for the exhaust air deflector.

These white tubes,from round styrene rod,are a necessary detail.They represent the holders for the caps for the headlight electrical connectors.
