I am currently looking for some dodge dana 60 drive flamges for my 85 dodge axle with 30 spline shafts. I currently have selectro hubs and am willing to trade those or just pay for flanges
Spendy, but those are what you're looking for. You'll find some used, but it will probably take a bit, as there weren't nearly as many external hub 60's used compared to the later (91-93?) Dodge, Chevy and Ford internal style hubs.
I have seen a few friends make drive flanges from 30spl Dana 60 differential side gears, a plas/laser cut flange and a welder. They aren't pretty, but they work.
