bagin my 67, help please.

[rideharder]

i picked up my first 67 chevy, has 4" front 6" rear static drop. lookin to g as low as posible but my engine choice kinda limits his..... dam CTD being so dam tall. i will be 3/4 ton up front to match my d70 8 lug patern.


still sbc drop coils...... saged out a little bit. but would like this to be my ride height.
im new to this air ride thing so, my quesins are
1. do i want my bags extended to say 1/2, 3/4, 7/8 of full travel at ride height?
2. my front x member should be 1.5"-2" away front the ground at full drop can this be achieved just from a bag or will i need drop spindles aswell?.
3. are single or double convulted bags better up front? or is it just the amount of lift u want/room u have to work with?
4.the 12valve cummins weighs a bit more than a sbc with the tranny it should weigh in at 1500-1600+#, 2600# bag will still be fine right...
sorry if some of thies have been beat to death but couldnt find what i needed
