Have you checked out Dave Strickler's "Old Reliable" 1968 Camaro Z-28 at
www.z28camaro.com ? Jerry offers some very cool component restoration services, books (The 1967-68 Z-28 Fact Book, The 1969 Camaro Fact Book Z-28,Z-L1,L-72,COPO etc.) Certification services too. Very cool, if you have anytime I would recommend it.
