Dropping the rear of my 64, what to use.

I just found a guy on ebay selling alot of the rear suspension spring related stuff i need. Im getting the spring brakets and shock plates from him, but i found another guy on ebay who had the spring hangers with the 1" drop option hole (just incase a 2" drop from springs or blocks isnt enough). The hangers eye holes are big enough for a 5/8 bolt, which means when I buy my bushings, i need the bushings that will be large enough to fit the 5/8 bolt hole right? I assume all the basic leaf springs have the same size hole where the bushings press into?
I also found Summits store on ebay and asked them if they had QA1 single adjustable shocks for my year car. Im sure they can get them, but i havent heard back yet. Does anyone have these on the rear of thier cars?
After i get everything spring related, Im going after the differential, then brakes. After that ill have all my suspension pieces....oops almost forgot i still need a rear sway bar. Id like a front sway bar but Bill at RMS doesnt carrier one for early A's, so ill have to have a custom one made (alterktion up front). Bill told me not to get too thick of a bar up front, because the alterktion was abit stiffer then the factory K frame (at least i think thats what he said). He went ahead and welded on the pieces where a sway bar could mount to though, so i wouldnt have to do it later (nice guy). I figure maybe later when my cars on the road, i can drive it to a shop who makes them and they can take the measurements and make me one to fit.
