looking for a set of factory schematics for chassis and engine for 86 trans am

This guy did an amazing job. They're all 1985 diagrams but should be close enough for what you need. Or get you started.

1992 Z28, 305 TPI 5 speed, 12.1 sec @ 114.7 mph

1984 Berlinetta 305 TPI Auto, 13.8 sec @ 99.7 mph

Hey Tim--do you know if there's any diagrams available for an 89 T/A? Vacuum-wiring--anything in depth?

I've got a bunch from the Helms manual for my '88 TA here...
