BALDWIN MOTION CORVETTE VINS?

[DandyDon]

I am looking at a 1971 Corvette that is thought to be a B/M car. It stared life as a real LS6 car and has most of the major Motion mods: Motion hood, flared fenders,old style Ansen Sprints, 4:56 rear with Motion bars, Hone-O-Drive, M22 with Hurst Super Shifter,Phase 3 CD, 3 barrel Holley,Fly Eye air cleaner, serious cam. The car does NOT have a sloped rear window or exposed headlights with covers.
It has original pop up headlights and a vacum tank to raise
them due to the wild cam profile
The seller claims the original owner did not want these items.
I'm guessing this is a customer car that may have beem modified by Motion Performance or a "catalog car" where key items were purchased from Motion.
Does anyone on this forum have a list of actual B/M Corvette VINs?
I have heard dealing with Joel Rosen is a tough experience.
Poor memory plus poor records have equated to clone cars being dubbed authentic and vice versa.
Any tips?
