I've been crawling around underneath Slambo, with the hope of smoothing out the tail. Started cutting up some cardboard this week, went a little nuts with the fiberglass.
Stage One:
First Test Fit:
I will try fastening it to the bumper with knockoff/OEM body panel clips (with a little duct tape insurance). Not sure where/how to fasten the front to the trunk floor. There's one spot that looks prime for drilling. Need to get Slambo up on ramps (better yet, a lift) to find additional fastening points.
Resin is a LOT less expensive if you buy it at big box home improvement stores, rather than auto part supply chain stores.
