im sure there are plenty of threads on installing the floor pans. Just use the "search tool" in the forum and im sure it will become your friend quickly.
Im sure though, If you cant find something just post it up and you will get tons of good answers. there are a LOT of top notch builders on this site that love to help when ever. good luck and get that inline six out and replaced soon as you can! hahaha
I am glad to see another young man spending his time on a constructive activity.I also saw a 70-73 camaro in one of your pics.What a coincidence I have one too.I've just finished stripping it down and doing some of the measuring and planning for my conversion.I see you aren't wasting any time in getting it on the road to driving it again.Consider your time now without anymore responsibility than you have a blessing,cause a wife,a couple of kids and a mortgage and possibly remodeling and things like that can really put a drain on your time and energy.I commend you for your energy and drive to get things done,and I wish you the best.
