are you sure you want to ditch the air ride? it's actually very very easy to install, perhaps easier than a spring setup because you are taking out the entire assembly out and putting the whole new assembly in, no compressing springs or anything like that. it's just 3 bolts on the top of the strut mount plate ( like 10 or 13mm bolts I forget ), and one big bolt at the bottom which you will need a very strong drill for ( regardless of what route you take, you will need a very strong impact wrench ). the drill I used is a Milwuakee mid-torque, do your homework and see what ft-lb the settings have on what ever drill you have or are looking into getting, because that bottom bolt is roughly 450 ft-lb torque that it needs to be re-fastened to.
it looks like amazon is out of stock right now, but I can't imagine they would take that long to restock. you can look at other websites or contact them directly, Suncore is the brand.
when I bought mine last year, it was 491$ for the pair of complete assemblies, you can get the price down by only getting partial assembly however it's very very easy and worthwhile to just get the complete assemblies and do a clean swap of old part / new part.
