That's the problem with Pull-A-Part . . . they don't sell whole cars, only parts from them. Other than the suspension and glass, just about everything that can be remove has been removed. I would say it's too far gone to think about saving . . . but I've seen your double cab, so maybe it isn't!
If you want to talk to them about it, Pull A Part's # in Atlanta is 770-242-8844. The bus is at the "Atlanta South" yard and is listed as a 1958 Vanagon . . . it's sitting in their "old cars" section (row 100) and it's been there since December 9th.
