WANTED: Original GM Spark Plug Wire Heat Shields + Bolts for 1968 Camaro SS‑35

[MartyW]

I’m looking for authentic GM assembly‑line or early-service spark plug wire heat shields and hardware for a 1968 Camaro SS‑350 (L48). These are the small‑block stamped/galvanized steel shields used on the driver and passenger sides.

Parts Needed
Heat Shields
* GM 3845621 – RH (passenger side) spark plug wire heat shield
* GM 3845622 – LH (driver side) spark plug wire heat shield

Requirements:
* Original GM only (no reproductions)
* Correct galvanized finish, stamping details, and geometry
* Light patina acceptable; no heavy pitting or structural damage

Mounting Hardware
* GM 447143 – Correct small-block heat shield bolt
* GM 274430 – Alternate/crossover bolt used on some service replacements

Preferred Hardware:I am specifically seeking original GM RBW or TR head‑marked bolts, black‑phosphate finish, no washers, no captured washers, and no bright zinc hardware.GM service‑replacement M‑head bolts are acceptable as a secondary option, but RBW and TR are preferred for assembly‑line accuracy.

If you have RBW or TR bolts—or complete shield/bolt sets—please contact me with photos of the bolt heads and finish.

Why I need them

These parts are for a documented 1968 SS‑350 survivor restoration, and will be archived in a judging‑grade binder. Accuracy matters—NOS or clean originals are ideal.

What I Can Offer
* Fair market pricing
* Immediate payment
* Happy to buy single pieces or complete sets

If you have these parts—or leads on trustworthy sellers—please message me. Photos of stamping, finish, and bolt head markings appreciated.
