Old Timing Gearset Design Needed

[MichBC3]

My machinist sent out my ATR RP309G camshaft for re-grinding/cleanup. Two lobes were pitted a bit due to some foreign material circulating around.
While my Turbo Trans Am engine is apart, I would like to purchase new timing gears. Because this is an old stick, commonly available gearsets with the large hole retained by two bolts won't work with it.

Additionally, this block was line bored in the past, so I need to get a 0.005" tighter gearset. Note that the chain dampener is not used.
Does anyone know of a vendor that still sells these?

RollMaster red label Buick v6 odd fire timing set. Full throttle speed will have it. Or TA performance.

Thanks. I failed to realize that this old gear design/system might have been what they used to use in the old odd fire engines. I sure appreciate the lead. I was beginning to think I might have made a mistake trying to save the old cam. I like the grind a lot. Has good vacuum at idle and seemed to pull strong to 5600 rpm (seat of the pants dyno). I am using 1.7 ratio rocker arms so that probably helps.
