Another Hello from Southern NJ

Just signed up and wanted to say hello.

I'll be a 70 340 Swinger owner in the near future,
And am looking for a good information source (which I'm sure I've found here at the A-bodies forum)
Where is the best place to find production data/figures as well as info on optional equiptment breakdowns?
For Example the car has a thumbwheel am radio. What is the difference between this and the post/knob type radio? As I've seen the 2 different styles of instrament panels on E-bay.
Also looking for the best restoration parts suppliers (poked around Year-One for a bit already)Although the car isn't in need of a restoration...just a few replacement and detail pieces to bring it up to par :wink:
This will be my first Mopar in a mostly Chevy corral.
Well hello, look forward to lurking, learning and asking more than a few questions once the car arrives home.
