Autoride Link Measure upon lowering

[ds99thoe]

Does anybody know what the lenght the links need to be at when doing a 1.5/2.75 ground force lowering kit.
The truck is a 07 Tahoe LTZ 4WD withe autoride and rear airshocks all factory. I got the kit for free and I am trying to piece together everything to make work on my truck. Also do I need shock extenders for the rear?
The kit came off or a 07 4WD Tahoe non-autoride. Any help would be greatly appreciated.

The shop I work at we do suspension, I am going to try and get some at cost, and I have all-thread just didnt know it anybody had the measurement. I know the McGaughys kit just jas you bend them according to their template. If I can't get the shock extenders cheaper than that I will take you up on your offer. Thanks.
