Use a sharp knife to separate the parts, then trim off any excess plastic.
Assemble the three parts of the roll bar using small drops of epoxy. The ends of the Roll Bar Supports have both a short and a long nub. The short nub attaches to the Roll Bar, while the long nub goes into the car body (see step 4 below).
If desired, paint the car parts with an acrylic or lacquer paint. Avoid enamel paint.
To attach the roll bar to the car:
Use a 3/32 inch drill bit and a drill (or a spare nail axle and a hammer) to create shallow holes at the pencil marks.
Attach all car parts with quick setting epoxy. (It is best to attach the parts after all other car preparation steps are completed)
Allow the epoxy to fully cure before handling the car.
