well my bearing in my a/c tensioner pulley died so i didnt have a/c for a good while.

I looked everywhere for the pulley but could not find one, asked for advice and i was told the KA wouldnt work so i called a local shop they said they would charge me $70 because it had to be taken from a known good engine.... BS

today went to the local junkyard found me an s13 with a KA24DE looked at the pulley looked similar so i said **** it pulled it off bought it $5...

the KA24DE A/C tensioner pulley is exactly the same as a redtop SR A/C tensioner pulley.

so im just posting this up for anyone with this problem so they can solve it quickly and cheaply and not have a/c for 3 months then find out you can get the part at the junkyard for $5 like me

btw im pretty sure its the same for the blacktop SR but not so sure on the S14/S15 SR's but $5 wont kill you
