Need a help with A/C crankshaft pulley

[Festiva GTX]

OK, I can't figure out how to install with 2 pulley set with A/C replace over one main pulley...

I just found out my 1992 Festiva L without A/C have different pulley hole size with four little bolts while I got parts with two set pulley (one main for alt and water pump and second pulley one for A/C)

Is there two different size crankshaft fitting? or what?

Anyone can help out with that?

Thanks.

The pulleys for 88-92 are different than for a 93. You might have the wrong year.

Uhmm... probably my new engine was 1993 but does have different kind pulley for AC on 1993 engine?

I wonder if 1993 and later aspire engine same size bigger round with four bolts AC pulley?
