Did a quick and dirty check to see how flexy my frame is. Just stuck a laser pointer on the rear fender with a magnet and aimed it at a notecard taped to the front fender. Marked the position of the dot, then jacked the wheels off the ground and marked the position of the dot again.
Have nothing to compare it to, but will check this in the future after some restoration work. If anyone is game to try this, it would be interesting to compare.    |

So the first dot is where the laser hits the card with the car sitting on the ground. Then I jack the car up- the jack point is the built-in jack point. This causes the laser dot to move to a new location because of frame flex and then I mark the new location.
I will repair the rusted longs and repeat the test. I intend to install some frame stiffening kit (Engmann kit and maybe more). Then I will repeat the test again and see if stiffness is improved. As I said, it is quick and dirty. I have no FAT man. :-( I used to drive a Supra with a targa top and there was a huge difference with the top off. It would be awesome to have a targa with a nice stiff frame even with the top off. |

Great idea. Use a piece of graph paper at the indicator end. The graph paper has 1/4" increments on both the vertical and horizontal planes. You could have real numbers. Did your drivers side move both up and over ? I'd expect to see the passenger more flexible. |
