The Rafael ( CFM Fiberglass Mexico), scissor frame carriage top requires their specific header bow , latch system. The scissor frame center bow is higher than normal ( I cut mine down ) top frame doesn't not sit quite flush when fully folded down ( mine does now after a lot of reworking ) requiring their quarter boot cover and the top snaps need to be further back on the body than normal if not using their rear bow to body tub mount . It worked out for me as it came with a project speedster but in no way would I buy one outright as it is overly labor intensive. Greg's Vintage Motorcars top assembly fits the CMC and when installed correctly it is 90% or better watertight. It is also a nicer StayFast material.
