I'll chime in that they aren't helpful at all to folks doing a rebuild. Told me they couldn't provide any measurements on the lift panels as they were privileged business info or some thing like that. Then in the next sentence, they said they would be happy to build some for me but I'd have to provide the measurements, and if they came out wrong, it was my problem! HUH? Called ATC, and they were more than happy to provide excellent info. I'd most certainly be looking at an ATC instead of a FWC, if buying one today!
