A little confused on why you called the grooves first and third and not first and second. A swp 2 groove pulley is for alt and ac. The first groove is for the alt and the second groove is for the ac. The ps driver pulley is seperate and bolts on in front of the first pulley no matter if its a 1 or 2 groove pulley. Hope that helps.

OK sorry i didn't give a pix... my pocket camera the little USB data connector is ruined...the pulley has the first inner groove and the 3rd outer groove all in one spot welded pulley...it skips the center groove so according to your info it is for ALT and P/S & without A/C. Thank you for the helP!
Update...I took smartphone pixs today of the 409 that's for sale...if i can figure out how to get pixs from the smartphone to attach here...the pulley is on it you can see it if you look close.

GM didn't weld swp pulleys together, Check out these Ebay ads to see what the pulleys look like. One is a single groove alt only, one is the ps add on driver pulley, and one that shows a 2 groove alt/ac pulley with a ps pulley.
