need help locating this idler pulley

[H W Bush]

it goes to my vortech v1 setup. it blew this week and allowed my belt to shred and left me stranded. I ordered the pulley that's listed on their website for the 96-97 cobras and it's way too small and the bearing I.D. is too small to my spacers. [FONT=Arial, Helvetica, sans-serif]VOR-4FK116-021 is wrong! [/FONT]so i went to advance and the best we could do is this DAYCO89161. The measurements of the old one are as follows
it's a smooth pulley
2.5 inch diameter by 1 1/8 width
or
63.65 diameter by 28.67 width

so the new one is a little too narrow, allowing the belt to slip off the blower some. any help appreciated because vortech does not show what i had on their website!

Is the old pulley itself still fine? You can press out the old bearing and get a new one.

yes it is. just a little marred on the edge. was just thinking this with a parts store guy. where can i get a nice bearing for it? he suggested pressing out a new pulley bearing (socket&hammer) and putting it in the old pulley. but the thing is i won't be tackling this job again till the weekend since it's my DD so i can wait anyway.
