Mr48chev: Good call on going underneath first for measurements, and yes I planned to view the pics from dsraven full size on my home computer vs cell phone.
My apologies if this has been gone over before, and I mean no disrespect but I just joined and don't have the time to surf through hundreds of pages. Don't get me wrong, it's a great forum and loads of great info on here and seem like a great bunch of people. Just wish maybe the moderators would separate the AD and TF trucks, would make the specific info surfing faster. But then it's nice for both crowds to share info and experience!
OrrieG: not switching clips, like I said have both complete trucks. Although the 55.2 does have a '57 hood from previous owner! My thoughts were to take my 55.2 cab, whole front clip, and rear fenders over to my 59 chassis and box sides (59 rear fenders & tailgate are really rough) So I end up with the big window, short box, step side I've always wanted
Reason for my madness is I'm thinking of getting the Porterbuilt front & rear dropmember systems, and I know those units use the factory rivet holes for locating. My caution is if the length isn't simply in the front of the frame "horns", then the rivet locations might mess the geometry up for the PB units. So hopefully I can use the info from the gents above when I get back home and if luck is on my side the extra frame length is in the front tips, but then I've got no luck! Lol
Thanks again all! still surfing the pages and finding answers and new thoughts on ideas and how-to's for my project.
