Xelmon and I did some quick tape-measure checks on a Sportsmobile poptop last summer when we saw one at a campout, it was an extended-length Econoline 4x4, early-to-mid 2000's if it matters.
The poptop measured out within 1/2" side-to-side and within 1" front-to-back compared to his '68 90" Sportvan. The shape where the fiberglass hits the roof is obviously different, but it wasn't too far off and could probably work with a bit of trimming.
Just need to find one in a junkyard somewhere. =D
