I am looking for sources of information on how to build a "soft" top for my roadster pickup. At this point in time, I am not sure wheather to build it to fold, or to be a rigid "Carson" style top. What I envision is --build the tubing structure out of thin wall electricians EMT metal tubing, bent with either a bending jig or electricians "Hickey", fabricate hinge points from light bar stock (or if making a Carson style, weld the pipes into finished shape). The roadster pickup started life as a sedan. so the windshield posts were cut off at the roof line and filled with a 3/16" plate, with a 3/8" nut welded on the inside, to accept bolts which would hold some form of header. ( the windshield opening has been modified for a glue in windshield, which will not normally run any header. I will have a local marine shop which sews canvas boat tops make the actual top fabric covering.----if anyone out there has done this succesfully, I would like to hear from them.----I have also seen where people running Carson style tops use old seat belt buckles to connect the tops to the car body structure.---buckle with latch is built into top, tongue which fits into latch part is attached to body, (or vice-versa if you don't want the tongue sticking up to catch your arm when running without the top). Any help or pictures would be appreciated.
