[Spridgets] seat upholstery availability question

[Bud Osbourne]

My '73 Midget is rapidly approaching the painting stage (actually, the
underside is primed, 3M Body Schutzed, and ready for me to apply color
tomorrow), and I've been thinking about some of the multitude of small
and not-so-small items which will need to be taken care of, to finish
the restoration.
One of my wife's pet peeves with old cars, on long trips in summer
weather (the trip to Lake of the Ozarks, to be precise) is vinyl seats.
Does anyone know of any upholstery, for a '73 Midget, that features a
cloth insert like those found on B-GTs of the same vintage?  I haven't
checked with any suppliers, yet, as I was hoping one of you folks might
be able to save me some search time.
I guess we could just use the "sheeps-peltz" seat covers that she bought
for our '72, when we took our last multi-day, 2000 mi. Midget trip
(1984), but I just don't like the look of those things. 
Thanks.
