I'd strongly suggest pulling the whole front clip (bumper first, then grille, radiator and bulkhead, fenders, etc. as one chunk). It's a lot easier than it looks, and darn near everything you touch (wiring, bolts, should be given a clean up and look anyway.
I've done this on a couple 40s cars and a mid fifties car.
You WILL need a friend to help get it off, but it sure makes stuff easier to pull.

For flatty info, the P15/D24 site is your best bet.
The Imperial club site may have some useful stuff too.
