Q#1 -the "headmarks" on the 2 bolts on the aluminum thermostat housing ? and were they cad plated or natural?
Q#2 - the "headmark" of the bolt used on the distributor hold-down bolt?
Also i see in a paragon book that the throttle return spring on a tri-pwr is said to use a small bracket on the back carb base , alongt with the cable clamp bracket. I see a small hole in my cable clamp down bracket and am wondering if this hole is for the spring and did not use this small piece ?
