looking for double adjustable rear shocks

[pfordamx]

I"m looking for some good double adjustable rear shocks. the car is a 69 amx, howerver going by a few sites it appears the rear shock setup is the same as early camaros and mustangs, the car has calvert monoleafs and bars. next year should weigh about 3100 and make around 670 hp and were using MT pro bracket radials i was originally thinking AFCO's but can't find the configuration i'm looking for might need to call but i wasn't sure if strange or qa1s where any good i've looked at Vikings was hoping to find a bit higher quaility than that though but i also can't afford santhuffs.
