Date coded plug wires for Oct 69 build
My 1969 L46 was built late October 1969 (extended run for 1969 remember). Date coded plug wire vendor listings normally show for a specific model year application two options: "3-Q-xx" and "1-Q-yy" where "xx" is the year prior to the model year and"yy" is the model year. Model year production usually began in the Fall for the next calendar years cars. But that doesn't address something like the late run of 1969's well into the Fall of 1969.
So, in the case of a 1969 Corvette built in late October 1969, I think the correct date code for the plug wires would in actually be "3-Q-69" (which, in vendor listings show that for 1970's).
Would this pass muster with NCRS ? (Not a current member so I can't pose the question there).
Thanks for any and all comments/suggestions.

Unless a carb or starter malfunctioned they would pull off the precheck list before loading on the train. They will put on a carb or item still dated late but before assembly date of car.
So the question to your answer is
Yes
most likely a 3 Q 69 or 4 Q 69 would be better but not a 1 Q 70 dated plug wire
There may have been instances they used 2 Q 69 as the plant wants to get rid of parts on the assembly line
Join up NCRS.org and then join up a local chapter. Member ship is so cheap for the amount of information you can receive

Production for 1969 Corvettes started in the fall of 1968, so those would have had a "3-Q-68" coded wire set. As I understand it, that would have been used through calendar year end, and "1-Q-69 used for the remainder of the model year, starting in January and evwhich normally would have ended around June 1969.
Since the 1969 model year production ran almost to year end 1969, my thoughts are that wires coded "3-Q-69" would have been used. They would have been used even if 69 production had ceased in June and 1970 production had commenced by late summer. So in essence, regardless of the model year being built in the Fall of 1969, wires would have been coded "3-Q-69"
Does that add up ?

Would not be surprised to see 1-Q-69, 2-Q-69 and 3-Q-69 intermixed I have seen this on original Corvette's I have judged. My 1971 LT-1 built Sept 1970 had 1-Q-70 and 2-Q-70 wires.
