Kenny Davis a member here on CHR with the sign on name of Kennyd deals with willys bodies a lot. he probably knows somthing about them. I'v heard of Active power and my dad was considered using 1 of there kits. Kennyd told me that they are poor quality and wouldn't have a good resale. if you want to put a Willys on an S10 frame, you do not need an active power body to do so, any aftermarket '41 willys body will fit on the S10 chassie, Active power is the only 1 that advertises it. PM kennyd to see what he has to say
