I have a 85 turbo motor sitting on the garage floor now.
The top is screwed onto the Raider top with self tappers.
There are some more self tappers going into the inner body on the rear.
I will add some turn buckles and hooks on the side of the body by the rear wheels.

Well on my way to becoming that eccentric old man in every town.(crazy as a s#@thouse rat) With a yard full of desireable old vehicles that tells you, Sorry they're not for sale..... Someday I'm going to fix them.
