hey guys been using winters qc's in compact speedcars and midgets for years , you will have a few mounting issues to overcome if you are keeping the leafsprings , they are ment for 4 link raccecars or super sedans that have all sorts of torque arms and link arms but im sure it can be sorted out, only other issue is that it is a "race" diff with gear geometry to suit ,that means you wont be able to hear yourself think inside the cab when moving so remember the ear plugs!
