I sent you an e-mail. I also pulled out the master and compared it to the most current castings I made yesterday and found them to be spot on as far as overall width when compared to each other. If anything the inside of the uptop around the back got a tiny wee bit thicker (on the inside) but seeing how the molds are now old and have produced nearly 200 copies each I am amazed at how close the castings still are to the original. If you can respond through e-mail with a width measurement across the opening in the back (where it would meet the body behind the door line) that would possibly help me figure out what is going on. I can also send you some photos of this uptop on the Monogram deuce roadster body so you can see how it should likely fit.
