Mike:
I'm looking through my '72 dealer album - specifically the LeMans order form now to see the "hows" and whys" of the WW5 (704) Y99 (724) and the PJ4 G60x15 tire options.
It appears that one could indeed order the Y99 handling package - which included the G60 tires, power steering, special springs and shocks, and F & R stabilzer bars on ANY '72 D27 (post coupe) or D37 (hardtop coupe) LeMans. Wheel style is not mentioned.
There was also a Y96 (621) firm ride and handling package offered. It included firm springs, shocks and stabilzer bar. No mention if the stabilzer bar was a stiffer front bar or an added rear bar.
The WW5 option package, including: 455HO, TH400 or M22 4 speed, posi diff, sport mirrors (hardtop only), unitized ignition, Ram Air hood, Formula steering wheel, roof drip moldings on the post coupe, carpeting on the post coupe, PDB, gauge cluster w/ I.P. tach, "GTO H.O." identification, and the Y99 handling package was available on GTO post coupes and hardtops only. Again, no wheel style is mentioned.
The G60 tires were available only on a GTO, and/or with the Y99 handling package. SO it appears one could have ordered a GTO with 15" wheels, without ordering the Y99 or WW5 options.
There was also a lesser known performance package option - WW4 (702). It was available on any LeMans post coupe or hardtop coupe, EXCEPT with the GTO option. It included: 400 4V, 4 speed manual trans, posi diff, PDB, carpeting on the post coupe, and the Y99 handling package.
No mention is made in any of these options and packages on wheel STYLE, although I seriously doubt that the 15" tires would have been available on plain wheels.
Interestingly, the LeMans GT is the only option package - including the GTO, which included Rally II wheels.
Later,
Lloyd
