If you measured it right, then -1 is a good place to start with solids. You want to try to get as straight a line as you can thru your driveline under load. With that said, solids don't flex very much. You want to keep it as close as you can without letting it go past 0 under load. Here is a good site with simple instructions. The hardest thing is to find a degreeing wheel. It is easier than using a level though. Good luck.
