What is the correct spare tire/wheel? '70 GTX

I have an un-restored 1970 GTX, Los Angeles built "E" with a 204 Scheduled Production Date (Wednesday, February 4, 1970).
No broadcast sheet!
The best evidence I have leads me to believe the car was originally equipt with 15 X 7" body-colored FJ5 steel wheels (part #2944 450) with F60-15 Polyglas GTs (with size in RWL).
----- No red paint on the rear 10" drums. Car has power disc brakes.
----- Spacers under the rubber stops on the Lower Control Arms.

So ... What is the correct spare?
TIRE ----- F60-15 Polyglas GTs (with size in RWL)?
WHEEL ----- #2944 450 painted black or "limelight"?
other?

If I put 15 X 7" rallye wheels on it ... What is the correct spare?
TIRE ----- F60-15 Polyglas GTs (with size in RWL)?
WHEEL ----- #2944 450 painted black or rallye wheel?

black 450 with steelies
space saver with rallyes

on a rallye wheel car , black 15" wheel and F60-15 with the size in raised white letters

I believe the spare with body color wheels is also body color , but the same 15" steel wheel and same tire as above

I like that clues like this can be used to figure things out.
