Update:
My air kit arrived the other day after waiting what seemed like forever for the custom-ordered struts to come in from AirRex. I went out to the garage to do a mockup with the tank, fittings, compressors, etc.... only to find that the struts and air bags are all manufactured with 1/4" fittings, not the 3/8" that I ordered!
Of course, the company I ordered from managed to get the other half of the order right -- 3/8" fittings, 3/8" AutoPilot v2, 3/8" tubing, etc.
Unbelievable!!!!
