Interesting thought Sid. I initially thought MMC wouldn't have the volume to justify a dedicated airbox moulding but then realised they do have one for the intake manifold complete with Morgan logo.
It still doesn't make sense for them to have a custom made airbox then take a hacksaw to it though. As well as the two Mustang airbox variants there were other cars fitted with the same Cyclone engine, Mazda, Lincoln, Ford Edge, F-150 and Transit even a Ginetta .... I wonder
