'74 Rear Susp service and upgrades

[Charles Freeborn]

Ok, so the major overhaul is going to happen another day, but meanwhile I'd like to adjust the ride height. Is there a formula for how many inner teeth up or down vs outer on the TB's change the height by how much?
I'd like to bring the rear on my stock '74 2.7, AC removed, 205/60- 15's, down by roughly an inch. Telling me how many degrees change the spring plates will move doesn't translate into usable data for me. Sorry, I'm not that geeked out (yet).
Thx,

OK, so parts are starting to pile up for this project. I've sourced trailing arms, hubs and half shafts from an '82 to bring it up to SC specs. Biggest question is what combination of half shafts and CV's will I use? My CV's are 4 bolt and the SC variety are 5, no? At what point will I transition to the '74 parts. I'd love to use the later disk, rotor and caliper set up....
Not too excited about breaking into the Transaxle to change the output flanges... at least not yet...

Any thoughts on the CV / rear hub combinations?

What sort of mods to drive flanges? Is complete trans tear down necessary?

That doesn't sound too painful. I'm liking the idea of switching over to SC parts. CV's, etc are much less expensive.
