Just confirmed that the driveshaft was not high speed tested. It was only taken to about 500-700 RPM and brought in to no worse that .005-.007” runout.

I am beginning to look at having a 3”, .0083” wall thickness, driveshaft built, that is .750” longer on the body to get more engagement in the trans.
