That's a good question. I've yet to find any of the QA1's for my application? Where do you get 'em
I got mine on Summit Racing for about $139/ea. IIRC, it's the same price for most all of their "Stocker Star" aluminum-body single-adjustable shocks. They have Mopar applications, but I don't think they break it down to A/B/C/E/F-body, etc. I actually have GM A-body shocks on my Valiant, since they are slightly shorter and a better fit for my lowered suspension. It was just a matter of simple tweaks (bushing sleeves & a 1/2" drill bit) to get them to fit perfectly.
I'm very happy with my single-adjustables, but will probably get double-adjustables some time in the future - after I get some more time in the car.
