If people are paying $599 for just a console top as I did from Ames for my 67 LeMans, I would think you could sell your whole "Burlwood 68 Firebird Kit" (console top & lid, ashtray, center dash piece, radio plate) where you have the customer send you their OEM pieces. You recover them & ship them back.
Your materials might be $100 and now just figure out what your time/labor would be, let's say 20 hours total @$20/hr. that would be $400 labor, $100 materials, plus shipping so let's say $600 total. To have a reconditioned console top and dash parts that look as good as yours, considering none of this stuff is available and even if it ever is, it would not compare to what you are capable of. Bang, there you go, nice little side business. I think you may get more customers than you might think given the alternatives available...
