Thanks a lot for the break down of parts you cast AND ESPECIALLY the techniques for making stock seating and door panels ! I can appreciate the efforts and your reasoning for discontinuing the conversion kit...what I can't understand is why Monogram hasn't put the parts that were available back in the truck kit ???
Because the original parts that were removed probably no longer exist. Comparing the plated tree in the current kit to one from an original, the parts still in the kit are arranged differently in relation to one another. That would indicate that the original tooling was reworked (possibly cut apart, or individual inserts removed from it and rearranged). When that happened, it was seldom done with the thought of putting it back together later in the original arrangement. At the time (early Seventies) the thought was probably "let's dump these outdated custom parts". Like the Tom Daniel kits show rod kits that were restored to original versions, reworking the Ford pickup back to the original near-stock version would likely have to be done with newly tooled parts.
The same type of alteration (rearranged parts) was done with one of the other early Ford kits I checked; if I remember right I checked the '30 Ford phaeton kit when I had an original one a while back.
