QA-1 shocks are available at jegs.com and they also are relabeled by Jegs and cheaper.
I have the shortest QA-1's on the front, single adjustable.
Jegs number 122-US301 Ultra ride with bearing ends & 300 lb 7" springs.
And Jegs on the rear, double adjustables.
Jegs number 555-64900 bearing ends & 450 lb 9" springs.
The shocks and springs may not be the best for the weight of this car.
It's just my starting point, we will know more after we drive the car.
Rear coil overs.

Will you be fabricating a bracket that mounts the QAs onto the top of the lower control arms?

Yes.
And I if I have to, I will fabricate it 3 times before it is ok. :-)
Pull the transaxle ...
and then lift the motor ...
Even if this front upper shock mount never breaks it just looks .... well ... I am pretty sure I know what you are thinking.

Yep, mine looked a lot like that. In fact, the rear didn't even hold up to the trailer ride to the house before it failed. Being I had high aspirations, I decided then and there to gut everything and build it back up to my interpretation of "correct". That was 6 years ago, and many $$$$$ later (yes, build three to get a good one of whatever is being built), but the end is near, and paint has been purchased.
I'm thinking you may be close. I've been running 275/450 (F/R) on mine, but felt it was too weak (especially for the front), so I've stuck a set of 450/550 onto the car based on some other analysis and the additional weight the car has taken on since 6 years ago. I may be comparing apples to oranges between the two cars in that there are so many factors that need to be considered in the spring rate calculation. I'm also using the QA1 double adjustables on mine.Originally Posted by Jerry
So, how do you get an odd length of spring (7" & 9")? I suppose that may be a QA spring though. The one set of QA springs I used had several extra coils as compared to other springs I had, which for the same spring rate then required thicker wire, all of which presented a longer coil-bind length and excessive weight compared to the other coil springs I've used.

Yes those are qa-1 springs. The front shocks I bought are the shortest qa-1's there are.
The rear jegs shocks are the shortest ones there are.
Front shock travel is about 2.5".
Rear shock travel is 3.88".
Wheel travel is slightly more in both cases because of the leverage ratio of the shocks in the suspension.
I don't think a Mazda Miata or the front of a Corvette ZR-1 even have this much travel and they are both heavier cars.
There are no sway bars, I can add them, this car is really low to the ground. Roll center is very low.
Maybe I will drive it 1st.
Terrys car is amazing. Everything is better. I could not do such a big project. I just need to mostly restore mine and that is plenty of work for me. It's more than you first think.

So here is a better idea for those front upper mounts:
I did this computer drawing and I could cnc cut it.
Ok Here is a shape that clears and attaches to the frame better.
