Buyer Checklist
⚠ Clone warning: A G in VIN position 5 is the only proof of a real Boss 302 — clones built from regular fastbacks are common. Always verify with cowl tag, engine stamp, and registry before purchase.
VIN position 5 must be G — anything else is not a Boss 302
Match the partial VIN stamped on the engine block to the car
Order a Marti Report for original color, options and dealer
Check the rev limiter, correct Holley carburetor and canted-valve heads
Inspect floor pans, torque boxes and rear frame rails for rust
Look for race history — cut wheel wells, welded brackets, roll bar holes
Confirm correct 4-speed with Hurst shifter
Check shock towers for cracks — these cars were driven hard
