Note that the above part numbers are for a 1968 Camaro Sport Coupe with Deluxe Interior. Convertibles with Standard Interior, Convertbles with Deluxe Interior and Sport Coupes with Standard Interior use different part numbers.
As for the P&A (Parts and Accessories Manual), scour ebay and some of the Automotive Book stores like
Faxon,
Bob Johnson's,
Walter Miller, etc...
HERE'S A LIST of automotive literature dealers I found online. This should give you a good start!
Be advised that they
ARE out there, but hard to find. And expensive when you do find one! My September, 1968 matched set (P&A 34 - "Parts and Accessories Manual" and P&A 25 - "Illustrations and Special Information Manual"), set me back $200.00 several years ago. By now they're probably in the $250.00
EACH range. But the deals are still available. I just purchased a 1969 Camaro and Corvair Preliminary parts Catalog for Canada (P/N X691A) from September, 1968 for $20.00!!
Good luck on your hunt...
