Good afternoon everyone,
I may have goofed big time, hopefully I can fit this one.

I bought a 2# pulley (1 piece) used for a '99. I understand the center bore diameter for the '01+ is larger, hence the '99 part won't fit.

Is it just the center bore that is different or is the 3x bolt pattern different too? I have access to a full machine shop here and if it's only the center bore, I can fix it.

If it is just the center bore, can someone measure an '01+ pulley to let me know what to bore it to? I plan to measure the hub diameter, but a backup measurement would be helpful.

Thanks, Randy
