Exactly Mordy, I see taking this a step further with an expanding collet or
some other mechanical advantage to stabilize the skirt.
Great time spent with your son....my dad had me working on old tractor
engines at a very young age. He would be proud of me now, but wouldnt
understand that those old lumps travel at 120+ MPH.
My son Sean was handed a wrench at a very young age during the removal
of TR4A tranny. You guys dont hear much from him, but he is heavily
involved and a very fine driver of #197.
