track junkies/suspension gurus - i need some help

[jamba]

I'm getting my MCS dampers put on by Derek at AMS in Puyallup. we ran across a problem where my GC rear articulating adjusters don't have enough adjustment for my 9" rear springs. he also recommended that I get helper springs up front. rather than ordering from HP/Bimmerworld, etc. is there any local shops that would have rear height adjuster and helper springs in stock? Willing to travel anywhere as far north as the border or as far south as PDX.

if you have some of these parts on hand and are willing to sell, I'd be happy to take them.
