Too much $$. Should be less than $20 for a pulley. Shop around by phone.
$6.99 for a 6203 bearing that goes in either pulley. 2 appropriate size sockets and a couple taps with a hammer, viola....bearing out, then tap the new one in. Just note how deep the original was set and match the socket diameter to the outer race.
Fun times. I even disassemble, clean and grease those bearings occasionally. I'm currently evaluating a $16.99 bearing from NAPA (Napa part number 6203-2RSJ) on my idler pulley to see if it's worth the price for longevity. My tensioner has whatever bearing came in the new pulley as the "control".
BTW, John, I used to live in Spotsy. I'll be up there Sunday, visiting my sons.
