Hi all.
I loved this idea soo much, I decided to copy it. heres a few picss of my version, its a little different. I used pvc fittings for the gauge holders, and the all angled towards the driver, but all in a line ..... if ya know what I mean. I used expander foam and body filler, just the same as you did, worked great. if the bog is to thin though, the foam makes it a little soft underneath, so id say, use the foam only to hold things in place, then mostly bog for the shaping. any way, have a look Thanks heaps for the idea!
