Help with rear leaf spring bushings

So I have The smaller bushing with a 1/2" bolt. Can someone give me a good brand/ part#?
If still needed, I have a set of Energy Suspension for 1.5" eye I'll give you a good deal on if interested...
My slant 6, 7-1/4 rear, 75 Duster had a 9/16" bolt and 2" eye. :BangHead:
So I needed the larger bushings and had to open up holes on hangers for new 5/8 bolts. Had already bought the 1.5's that were 'supposed' to be in all the slant, 75's long time before, so were no longer returnable. Just sitting here gathering dust...
