1975-1977 C3 Spare Tire Lock Bolt 8-3/8" Inch Length 345476 - OEM Number(s) (345476)
Restore secure Corvette spare tire mounting with a correct-length lock bolt that properly fastens the rear hanger to the frame crossmember.
The Corvette spare tire lock bolt secures the rear of the spare tire hanger assembly to the frame crossmember bracket. Using an incorrect length bolt can prevent proper clamping, compromise hanger stability, or cause alignment issues at the rear mounting point.
This reproduction bolt is manufactured to the correct 8 3/8" length and zinc plated for corrosion resistance, making it the proper replacement for 1975–1977 C3 applications where accuracy and secure mounting matter.
