Apparently, these GM 10244209 brackets aren't available now, and it's a pretty easy mod for '96-00 GM diesels. Note that the 2 short bolts are for the BRACKET; and that on engines with 1 alternator, the short bolts are already there holding the radiator hose hook to the A/C bracket, so they're not really needed in any kit. The LONG bolts are for the alternator, but they're the same as the A/C compressor bolts.

The dual-alternator belt is 6 ribs 120.3" long; at O'Reilly, a Gates Micro-V AT K061203 is ~$52. Dayco 5061203, Continental 4061203

The 90x30x17mm pulley 12556504 is probably equivalent to ACDelco 38020 (Gates 38020) &/or ACDelco 36299.

Here's the kit I built:
