well took it out and hammered on it today up to about 90 mph on what I will call a closed course..... Vibration was much better. Tomorrow I'm going to fine tune it some. I came up with -4 at the trans and finished with -3 at the pinion, Today I remeasured with a better digital protractor and it's more like -4.3 and the pinion -2.4 so still room for improvement.

The only way to increase the critical speed of a shaft is to make it shorter or increase the dia of the shaft/tube and in the case of our cars we need to increase dia as the length is fixed. as I said above the shaft was spinning right near the true half critical speed for the dia and size I had installed

Just a bit of an update on the car and some winter projects I have been working on. I bought an Apex drivetrain crossmember which is basically the same as American powertrain but in steel(not sure who was first to market). They make a bunch of parts. https://apexdrivetrain.com/ This mounts to the stock holes and is modular to fit multiple transmissions. Secondly I finished up my console and installed it. The shifter works great doesn’t look totally stock but at a quick glance…. Had I not been in such a hurry initially the patch panel would not of been required most likely

Living in Canada I purchased from a local supplier, This was to cut out the excessive shipping and if I had any problems down the road easy to deal with warranty etc. The shifter installed is the same one Modern drivetrain sells with there kits its made by https://redrobertsinc.com/ I would consider what I had to do a bolt in, But If I had to do it over again I would get the shifter mentioned below just to save a step or two. The trans was installed January 2021 and has about 2000 trouble free miles so far and I love it.
