You might want to look at a local canvas shop...looks pretty similar to a boat type cover...

 

i have snaps all the way around, but is love it. there is a rubber seal that goes all the way around and i never had a problem even going 70 in a thunderstorm. i have mine made at a canvas shop. it cost about 385 and has lasted me 3 summers soo far. and the truck looks sick with it on, i think it looks better then the tonnau covers and the full size square backs. i'll get a picture of it when i go home and put the soft top on and then i'll post it for you guys. give me about 4 days. i'm at school now.

 

Is the STC top the fastback tonnue style?

 

put an ad in the paper in the wanted section "Old lady or equivilant to make a canvas top for my bronco" lol
Seriously tho, Id make mine before I paid for one...all it is, is a rag and some snaps.

 

had mine done at a local shop that does apolstery work. Think it is more "fastback" than the outhers pictured see galery. I also have a tonaeu that I modified from a short bed PU toneau for 40 bucks bioth are great but the kids do not fit under the toneau style.
