my question is if i remove the floor pan is there a chance that it could distort the body without the floor pan in should i weld some kind of a brace from door to door or something like that and the same for the trunk pan thanks.:confused:

With the post car you really shouldn't have to worry about bracing the door openings. It is the strongest body design because of the post. I just got finished with floorpans and trunk floor on my 65 and there was no difference in the door opening measurements afterward.
If you have to do rocker panels, then I would brace the doors.

thank you for the info.:beers:

I forgot to ask if the body is off the chassis, if you are doing the floors with the body off I would tack a brace between the doors at the rear of the opening just to be safe. With the body on, the mounts should hold the width just fine. I did the floors and trunk with the body bolted down and then pulled the body off. (1st time for me, pretty scary:confused:) Do you have to put in new seat braces? If not you can skip the brace, they would hold the width. - Mike
