You are correct, there are 2 different types of coil overs for Mustang II suspensions,
the first and easier upgrade changes Upper and Lower a arms, the lower still maintains the strut bar or not (your choice, you'd need to weld a bracket for a lower tubular a arm if you want to eliminate the strut Rod). This set-up uses the "stock" upper coil spring perch and shock mount while the lower A-Arm hold the adjustable coil over and shock. Fairly quick and easy if you elect to keep the lower strut arm, just replace with a tubular unit with poly bushings.
The second and a little more involved is to go to "true" coil overs where you also need to cut off the upper "stock" spring perch and shock mount and weld in a new upper coil over shock mount or perch. Your coil overs in this set-up would then have a single bolt in the upper mount and a single bolt in the lower a - arm. I don't think these are done to our cars very often due to complexity of suspension geometry. If you weld the new upper perch in wrong, suspension geometry will be affected. This is not very difficult to do, just requires patience and good measurements. I'm I-Car certified welder and have my own TIG and MIG machines, so I'm not worried about that.
I'm leaning to #2 as I think it's a cleaner look and I believe provides more adjustability options. Also, one of the fundamental problems with MII suspensions that I have never liked is when you take weight of the front suspension (when the frame is supported by a lift or jackstands), the downstop that carries ALL of the unsprung weight of the car is the upper shock bushing. In stock MII cars, this frequently destroys the upper shock bushing and also can damage the internal shock valving if left for extended periods (Like 4-6 months of storing on jack stands to eliminate tire flat spots).
Is this what you were referring to?

Yes. See although Ive been welding since I was 5, 45 now, I still just play one on TV. I do have a speed shop that has a TIG&MIG they said I could use or pay them to do. Probably will do the latter.
If I'm hearing you wrong my appologies but what if I juat replaced the whole set for something like this except the Wilwood brake set up that I already have in place?
Plus does it look like coil over QA1 will simply bolt on at the back of 8.8 rear or do you think there will be clearance issues?
Thanks!
