Somebody should come along on here by this evening who has the data for 455cid LeMans Convertible .
All my files and data are trapped on a laptop right now.

Looks like Guide Lamp (bulbs and lenses) bought the car new through fleet wholesale type program. The 60 in the 60-093 is a fleet wholesale type account.

Highest likelihoods are a company car for vested employee , or an actual employee purchase. It could have also been used for evaluations of their products ... on paper ... or actual.
If you get my drift.
Like the Inland MFG car , and the AC Spark Plug car that were 60-xxx before.

09-545 is the dealership that it was delivered to for new car prep.

PPT 411689 .., the T is a billing code
Since I can't compare my files right now , memory thinks that is a fleet code.

Door jamb shows April built which could have been any day in April.
Invoice shows May 1st ship date , so likely it was built out in the end of April.
If that is correct , this will be the only invoice for this car.

What is the build week on left side of trim tag ?
Such as 03D , 04A , 04B , 04C etc.,...

Thanks for sharing your car and invoice with us.
Believe the Performance 455 is the 455cid engine YC code with #66 heads.
I don't think that is the 455 HO option.

A 71 GTO 455cid Convertible just sold at Mecum and I think its production was listed at about 90 cars.
Yours should be lower than that - possibly much much lower even in the teens or single digits perhaps.

The. 455cid engine wasn't chosen very often in the A-Body or F-Body
