Default Pulley and fan clutch question for 73 TA restoration

I am adding AC to my 73 TA non-AC car.

1. The pulleys I got off another AC firebird has a larger double pulley on the crank. (outer double is 8", inner single AC pulley is 7"). The double pulley on my non-ac car was 7". Which double pulley should I use? (see picture)

2. Pictures of other 73 TA's show a fan clutch. My car doesn't seem, to have one. Are fan clutches unique to AC cars? If so, where can I get the correct fan and extention parts?


Note lower pulleys and fan assembly

The flex fan blade & spacer you have on it will also not be correct for A/C.

What does the correct fan, spacer and clutch for a 73 TA with AC look like... and does anyone have a spare laying around?

I did the same retrofit on my car. I started out with the fan clutch but removed it and went back to the non AC flex fan. The fan clutch assemble just made too much noise! Sounded like a toyota mini truck when it was clutched up! Don't remember the diameters but the water pump one is smaller od and the crank ones larger.
