Re: M-19 Turntable?
Kevin:
My M9 has a plate mounted across the two engine angles. In the
center of that plate is a 1/2 inch pin 2 inches long. That pin
fits into a piece of pipe welded to the top of a sissors jack.
The jack is not attached to the car and when in use the jack must
be lowered onto a block as high as the rails.
Used very seldom because I have to carry the jack, handle, and
block in the car. Another car had the jack permanently mounted
to a similar plate, but still required the block.
You cant use a small jack because the Nissans had three wheels on
the ground while you jack up the fourth. It takes a STRONG jack
to lift the entire M19 and not collapse sideways. My jack is
strong and the pivot points have been reinforced.
