New member restoring 1950 3100, a few questions

[O.C.Barry]

Hi Folks - I'm new to this site, I'm restoring my first old truck. I've done a lot of restoration of classic Corvettes and have built a number of offshore race boats, so I'm not totally green. The truck was really rough, but I felt the old girl needed to be brought back. We've already installed a Heidt's front suspension and we've installed some of the cab patch panels and floor which I bought from Classic as well as some parts from LMC. Luckily the hood and roof are pretty good, but I'll have to replace the inner fenders, fenders, and bed. Here are my three pressing questions:

1.) Who sells the best built, most accurate door hinges? I'll buy a set of NOS if I can find them.

2.) Who sells the best built, most accurate body parts?

3.) I have a 2015 Chevy 1500 and I really like the ride; has anyone used 2015 Chevy 1500 rear springs in the 47-55 trucks?

Thanks in advance for your help.
