The very last chapter of the factory '67 Firebird Supplemental Service Manual has some real gems. Like how the factory installed the clocks and hood tachs:

Accessories


2012 Mustang Boss 302 #1918, Competition Orange. FGF replacement
2006 Mustang V6 Pony, Vista Blue. Factory ordered.
2019 BMW X3 (Titled to the wife, but I'm always driving it for her. So I'm claiming it)
Old projects, gone but not forgotten:
1967 FB 400, original CA car. After 22 years of work, trashed by the guy who was supposed to paint it. I had to sell it.
1980 Turbo Trans Am
1970 Mustang fastback, 351C 4Bbl, auto
1988 Mustang GT, 5 speed
1983 F-150 4x4, built 302
