My '72 Lemans PHS specifically states:

"HONYCOMB WLS" and yes, it is spelled that way. I do not know what two years later on TA's would show.

Honeycombs were optional on your LeMans, thus the notation on the invoice copy. My HO T-37 Coupe was ordered with 'em as well. Heavy wheel, even as 14x7's.
On the T/A's of this era, it's going to take viewing the wheel box code on the original buildsheet to know how originally equipped.
