Just last night I was surfing through the parts for sale forum, and saw a frame that has already been blasted and painted with por-15. I got to thinking about how easy it would be to have a frame next to my fj and just take things off of the the vehicle, clean them up and bolt them on the new frame. Then this morning I started to think of other implications of this plan. Specifically I was wondering what happens when the VINs don't match on the tub and the frame. ( I am in Maryland) I have a clear title on my FJ40, and would hate to screw it up for convienence. From some of the threads I have read on here, I get the impression that I would be better off blasting and painting my own frame and keeping the numbers matching. As a side question, should I register my FJ before doing the frame off, or wait til its done? thanks for any and all advice.
