94 ranger raising the back

I just bought a 94 ranger thats been lowered and c-notched the frame. It looks like drop spindles in the front. Anyway, id like to raise it back up so that the driveshaft doesnt hit the crossmember and so i can tow my mustang on a trailer. I figure im gonna have to get stock spindles for the front but could i just put air shocks on the back to get it up some, or should i also get stock leaf springs?

i would just get a stock leaf spring pack from pull-a-part or something,

shocks aren't ment to hold the weight up of the vehicle.

is the trucked bagged, or did he just take leafs out of the pack to lower it?
