Husker, “assuming The dimensions are correct” sums up the entire problem here. No one knows what the correct dimensions are for mixing and matching early and late engine screen systems.
An outside fuel door car requires an outside fuel door left-hand side cover. None of those side covers were ever installed with a full screen. Could the full screen cover work with the late side covers, who knows!!??
The early full screen covers attached with sheet metal screws. The later hump center covers attached with Dzus fittings. That is custom fabrication task number one
I do not know if all of the screens and all of the side covers are equal width. That is to say, what is the center gap between the early side covers and the late side covers??
if they are not the same then the center covers will not dimensionally interchange. Custom fabrication task number two?? Remember, we already need to rework the mounting system
if the center gap is different then early side covers must be used with the early full screen center cover. But, the left hand side cover for the all screen center covers were for cars that had engine bay fuel filling, not the outside fuel doors. So if you have to use all three early pieces you will have to customize the left-hand piece so it can work with the outside fuel door on Brian‘s car.
of course, we also don’t know if the later fullscreen center cover would even have sufficient clearance with Brian‘s intake manifold, carburetor and air cleaner.
Anything other than that is a crapshoot sure to require an unknown amount of modification and fabrication .
additionally, he will need to actually find and purchase a full screen center. Will that be $300 or $500 if you can find one? And after spending the money and finding it will not fit,……
The only easy solution is for Brian to give up on the full screen center desire and install the center that is correct for his car.
Brian, with sufficient no-set-budget funds available, no limit on the time and effort, the necessary skill sets and fabrication abilities, welding, and who knows what else, yes, you can have a full screen center cover.
Just how much are you prepared to invest?
