All, moving forward, everything is available until I take it down from here (no dibs). Too many buyers claiming they will take something and really just kicking the tires.
To save time... here are some details on sizes. My ship address is 91354. I recommend checking USPS, UPS, and shipnex so you know what it will cost to get to you.
Diffuser: 66" long, 15" wide, box maybe 8" deep, weight 10lbs with box (was 50-100 to ship)
Strut bar: 34" long if the towers are off.
Wheels: 25" x 25" x 11" assume 50 lbs for weight for delivery to cover it (have cost $100-$200 to ship all 4 depending on how close)
