Does the pulley on the A/C compressor in the 88 Duke have 5 or 6 grooves?
Thnx,

I think six, but don't know for sure. It's wider than the V6, IIRC.
Check your alternator or crank pulley if you can see them more easily.

I drove my Formula to work today, but I can check my duke this evening if you don't have a definitive answer by then.

Did you have a chance to check?

It was threatening rain when I got home, and I forgot about it. I'll try again this evening.

My pulleys have 6 grooves, or in other words, 5 ridges between the grooves.

Was 6 grooves a good thing, or a bad thing?

Probably better than 5.  More surface grip area.  Wider belt.  When Melanie had her 93 Grand Am, I replaced the alternator.  It chewed up the belt in 50 miles.  The auto parts store gave me an alternator with a 5 rib pulley and one edge of the belt was running up on the shoulder of the pulley.  I managed to get back to the parts store before they sent my core in, and they swapped out pulleys from my old alternator.
