Hope someone can answer this and in the next few days. I obtained an Glasstite canopy for an 97-03 F150 long box. At least that is what I was told. I used it on my F-250 temporarily and now I'm trying to sell it to a guy with an F-150 longbox extended cab. I'm pretty sure it came off of a longbox regular cab. I've heard two different stories as far as compatibility. Some say the longbox extended cab takes a different canopy from a longbox regular cab. Anybody got any input on this? I need to drive 600 miles round trip to deliver the thing and don't want to get there and find out it's not the correct fit.
