I am in the process of resurecting a 1972 CJ5. The Jeep is a six cylinder and appears to be stock with the exception of a very old shackle lift. I have just discovered that my left side spring packs ( front and back) are sagging about one and one quarter inch. I have pretty much decided that I want to go with stock springs and re-use the extended shackles.
My questions are:
1. With 7 inches between the upper and lower bolts on the front and rear shackles how much lift over stock height will my jeep have when I install the new springs?
2. Can anybody recommend any spring shops or off road retailers in the St. Louis Metro area? I am taking a week of vacation starting July 21 and would like to tackle this project at that time.
3. It appears as though my Jeep has a Dana 30 axle in the front and a Dana 44 in the rear. Were these axles available as stock items on a 72 CJ5 or can I assume that they were installed by a P.O.?
4. The spring packs on the front of the Jeep have 10 leaves while the packs on the rear have 9. Is it best to go back with this arrangement or is some other setup better? I may take the occasional excursion into the mud with some of my local buddies but this truck will most likely spend most of it's time on the road.

Re: 1972 cj5 suspension questions
D30/D44...yes, these were stock fo a 72.
If you want a stock configuration, the JC Whitney spring packs are the best way to go (IMHO) I believe the JCW 7 leaf pack at all 4 corners will give ya the best ride. If ya do a search on here you can find alot of info about this very subject
I have a 2.5" lift on my 73 cj 6 and it rides nice . It is a skyjacker . I have a dana 44 and a 30 front . They are stock . If you are going to do a lift in the coming weeks start soaking all the bolts with PB blaster now . If you dont have a angle grinder with cutoff wheels . You may want to get one . When I went to disassemble my 6 it was all seized even after a week of pb blaster . So most of the stuff got cut off .
I would go with the rubicon express 2.5 extreme duty kit and not go with a shackle lift to many problems and you can get the lift for just a little more than stock springs plus it comes with break lines, QD, u-bolt skids.
Get rid of the lift shackles, pre '75 CJ's have narrow springs, causing some wander with stock shackles. With lift shackles, the wander is terrible and if it is spending almost all its time on the road it will make you miserable. Since your replacing springs anyway, get your lift that way.
Good choice on the lift. For sure get rid of the long shackles. Not only are the springs narrow but by tilting your front axle your steering angle gets messed up. Your actually steering into the ground and will cause a lot of bump steer. Also your approach angle is affected allowing you to hit rocks and stuff with shackles.
