Yeah,theres not much to the chassis .I did add crossmembers and more rollcage.As well as making a dash out of some sheet styrene.To fill in the wells I used .040 styrene and wrapped it around a paint bottle then used a heat gun to form it.
Then I used tenax glue and glued it around the whellwell until I had built it up to where I wanted it.Then dremeled the backside to thin it down.Sounds complicated but it is fairly simple.
