I am going to be doing the floors in my 74 K-5 soon but that is the least of my worries, I belive that the body is tweaked, i can not get my doors to close, i can grab the windsheild fram and the whole thing will move, I belive the somhow the firewall is bent forward, i did use a comalong attached to teh a pillar and was able to get the doors where they woudl close but as soon as i took it off it went right back, When i do my floor i plan on replacing the Front floor supports also, should this fix my problem, i would like to get it so i can open and close my doors
