69 Exhaust Hanger Bolts

[Floyd B.]

Would anyone know the expected head markings on the exhaust hanger bolts for '69? These bolts are shown in the AIM on page J224, UPC-8, Sheet A3. Part #'s 9418821 and 9417950. I have threads that discuss this in detail for C2's but found nothing concerning early C3's.

Thanx

Hi Floyd,
Here's one of the 9418821 bolts from my 71.
I'd think the SB /// head mark "could be a possibility" for your 69 too.
Regards,
Alan

SB or SBC is the most common for 69-72.
