But your Carburetor should be dated later on,just before your vehicles Trim Tag date,since it was put on the engine after the Alt./Dist. were,and they used Liquid Propane and a Run Box to start the engine@ Tonawanda w/o a carburetor for safety reasons @ that exact moment.

Alternators were not installed on the engine at the engine plant. The alternator (along with its brackets) was a vehicle assembly plant item. The alternator (and brackets) are shown in the car AIM with part numbers (and the AIM does not show part numbers for any engine components that were already on the engine when the engine arrived at the vehicle assembly plant from the engine plant).
I would suspect that if a 68 was converted at Yenko, they simply reused the alternator that came on the car. So that should be dated based on the car build date, not the engine assembly date.
