Oil pump drive

[Mr. Hipster]

Hello. I'm not having any luck chasing down a couple of the drives for a center mount turbo application. Found a image on line that shows a couple part numbers: 2604-5801 and 86045801. Not doing well putting these numbers into the internet and would guess they might be too old for GM to give a damn about.
The drives are the shortest type, clamp flange surface is the top of the casting. Used would be OK, rather ask around before I start modifying parts.

All 6.5 turbo vans, and turbo hummers used it.

Be that as it may I offered 35 bucks, we will see. Maybe seller will deal a little. I got a NOS never installed harmonic balancer with triple shives last week for 100, seller listed for 125, took the offer.
