Option Group GO3

Does anyone know what Option Group G03 is? It is listed on a COA for a 73S.

Also, what is Beige/Tan Leatherette/36? This car has front leather seats that look original with vinyl rear. Is that what 36 mean?

I think G03 is air conditioning.

It does have A/C and I think it is factory bc it has the box with front condenser in addition to the rear deck mounted one. Does this electrical panel look correct?

Also, what is Beige/Tan Leatherette/36?

36 are Beige/Tan genuine leather with basketweave leather insert front seats.
Rear should have no insert and are leatherette/vinyl.

FYI,
codes 36-38 are for Beige/Tan genuine leather front seats, codes 31-33 are for Beige/Tan leatherette/vinyl front seats.

Yes, other than the replacement voltage regulator. Factory installed A/C should also have the windshield washer bottle relocated to a point up near the cowl with the appropriate mount for the bottle welded to the trunk floor.

Here are some more pics.

Looks like a factory installation to me. Your car also has the under-bumper protection bars for the condenser.

A few more. Is this radio original? What is the hole in the left rear engine tin sheet metal for?

[edmayo]

Radio looks original, hole in left rear sheetmetal is for a hot air tube off the heat exchanger that feeds hot air to a thermostatic flap so the air intake gets warm air while warming up.
