Restart the rebuild

Reply back from TF on balancer is the ridge is normal and go ahead with install.
I asked about torque specs, TF is 90 lb/ft with loctite. OEM is 135 ??
He said go 90....
Ideas?
I also compared/measured oem style balancer to the TF for "height" and it will be close for pulley alignment approx 0.04" difference with TF being shorter.
