Help on bagging 67swb chevy.

[The Big Green]

I know I want to buy from SuicideDoors. I want the Slam RE7's,7gal tank, and 1/2in lines. I not so sure on the rest. I don't want a 4link or anything, just a budget setup for now but something I can keep upgrading. I want the rear bags to go in place of the coils, with a notch. I don't want to upgrade everything later, so I want the bags, tank, and compressor the be done with for a while.

Any suggestions on other parts that would be good? A 7gal tank that could mount under the bed and out of sight? Good compressor, Viair maybe, but which one with the line and tank it make it come up fast. I'm so new to this and would like to learn about some things.
