FS: New double adjustable QA1 ProCoil conversion

[BBC71Nova]

I'm considering trying something a little different now with the front suspension on my build. I have a new in box QA1 ProCoil double adjustable, 550lb spring coilover conversion setup and the spanner wrench & thrust washer kit that I wouldn't be using. Retail on this kit is all over the place at 799@Speedtech and a little over 600? at the big joints I think. No idea why there is such a difference but I'm pretty sure it is the same kit. These came from Speedtech FWIW. I'll get some pics up if there is any interest.

I'd do $650 for both.

Thanks!
