Thanks guys. Tachs are Autometers. Nice try torkflight! But I can be stubborn at times. Like with the Clutchflite I ran for many years. I'am grounding box to battery with heavy wire. Welded stud to frame to replace thru the frame bolt for battery ground cable. New crimp on cable ends. Even opened up the tips on the male ends of the pin connectors. Big,new AGM battery. But now I need to pull the trans back out and see how to make room for that flex plate shield..... thanks for the input and I will post up results when I fire it up.
