Just my 2-cents but from what you are describing i would stay with the original
sheet metal and stick with lining up the old instead of going with all new,
complete door bottoms can be had to repair your original doors,and most other repair sheet metal repair panels can be purchased also. also remember fit and finish was not
even that great when these trucks were built and new. the fit and finish on my 59 stepside
was "WAY" off! (what were most of the trucks used for back then? "TRUCKS") fit and finish was more of a concern on the cars back then.
you should check out your Hinge Pocket area also as that is a Notorious area to go bad
and you will get no were on the alignment if this area is not taken care of first for you doors to fit right.
You might try to find someone OR better yet try yourself at repairing the areas!
the money you put into sheet metal could go towards a welder, just saying and your up to the task, and my Hat is off to those that try themselves because to me that is were the Fun is on restoring and fixing these old trucks.
Ok i will get off the soap box! Lol... But good luck and i wish you the best on your truck!
This is a Great Forum to find people that have been in your shoes starting out and have been in the same situation but are there to help you threw.
as was told to me, Don't look at the over all Big picture, just take one area at a time
and look at what Has been fixed and don't be discouraged
Good Luck!
