Cracked block!? How could anybody let covertible muscle collect dust for 24 years because she needs a new motor? Didja get it? Are those pictures from your garage? Do you have to be insane to jack a car up that far? Sorry, just curious....
How safe are jack stands on top of 2x4s on top of tires. Think safe! Don't you want to grow old and senile like some of us......Nice score on the drop top.
Yikes....... I'd build me some sturdy saw horses out of 6x6's if I was going to have the car that high overhead.
That's a death wish waiting to happen. I take it you're trying to clean up the underside of the car ?
