Help Identifying Current Lift

I know little about suspension so will say that up front. I"m starting to learn more as I research but hopefully I'm not creating confusion if I use terms incorrectly etc.
I'm looking for help identifying how much of a current lift I have on my project over stock height. A PO added the lift. I believe it was skyjacker but not certain.
I'm guessing it has a 3-4" based on reading various suspension threads here during research. I'm also running 285/70R17 tires and have plenty of room in the wheel wells.
I don't have much difference on the front end between full droop (22") and at ride height (20"). I've been told by Fox, and several other shops I need at least 4". I've also been told it's likely due to the leaf springs (stiffness, length etc.) or shackles or combination thereof. The rear iss 22" at full droop and 18 3/4" at ride height so appear to be as expected.
Front springs are a 4 leaf pack, rear are 6 leaf. Driving will be 90+ % on road, light fire road for camping etc. no hard off road.
Does anyone have an '83 in stock trim that can measure the distance between shock mounts, center to center of eyelet?
That will give me a good idea on how much lift over stock.
Crown Automotive stock replacement shocks measure "Front Left or Right Shock Absorber; Lengths: 20″ Extended, 12-1/2″ Collapsed; One Eyelet Has a Steel Sleeve through It, Other Eyelet Does Not." I'm guessing that might = a 4" lift but not sure that is how it works.
My current plan is to keep the same lift height but replace the front springs.
Also, If I wanted to go a bit lower on the lift, say 2", if current lift is 3-4" would that have an impact on driveline at all? I'd like the angle on the rear shaft to be a bit less. Would a minimal reduction in lift or even return to stock (not planned would have to replace tires) require a new rear drive shaft.
A few pictures of wheel wells and front springs if useful.
