Baggin' the new Burb Question.

[jorgensensc]

My wife wants me to bag the burb, so that she can get in and out easier. It is a 3/4 ton Big Block '72, with coil rear end. I have an compressor setup from Arnot that I was going to use in my truck, 2 valves,1 dual needle gauge, with 2- 6" bags from Slam Specialties. I was setting it up in my truck so either back bag could be aired individually for load leveling, etc. My questions are:
1) I know everyone is saying the 7" and 8" bags are better for the rear of the trucks. But can I use my 6" bags for the front of the burb?
2) If I get 7" bags for the rear, will that be enough? Or should I get 8" bags for the rear?
3) Will the cups and plates for the front a-arms on a 1/2 ton work on the front A-Arms on the 3/4 ton? There are some on the parts board I may get if they will work correctly.
4) Do I need to get drop spindles? We are not looking for a crazy drop, but the burb is way too high for her right now. If so, Do they make 3/4 ton drop spindles? Who sells them?
Thanks for all the help guys!!
