1973 Pontiac Firebird Formula 350 4-speed, Rusty

Fun daily driver for me and my daughter for the past 17 years.
Pretty rusty, some in doors but mostly in rear. Driver's floor pan is rusted where parking brake bracket mounts. Rust around rear window. Body is otherwise straight. Runs and shifts fine but is tired. Noisy trans and noisy Positraction rear end.
Good dash. Door panels good but front seats are cracking and top of rear seat is cracked. A couple headliner seams are letting go and have been hand-stitched. Front carpet worn, rear is serviceable. Rear defroster works. Gauges all work except clock. Electric trunk release. Center console not perfect but pretty good.
Some spare parts available. 355 rear end, trunk lid, power door lock kit.
Will deliver within reasonable distance of San Carlos, CA for an agreed-upon fee, or pick it up yourself or or set up your own delivery.
