Did it scratch up the upper radiator support or does it clear everything ok?
I keep the tubing about 2-3 inches from the radiator support at the bottom...
I lower the crane arm down so it is about 2" above the radiator support so when you lift it it is mainly straight up...
I've used this deal on 4 different cars A and B and a friends E Body with LA...B and RB engines...
No issues...
If you notice how tall Kerns cart is that makes his car need to be higher...
If mine was that tall I would need to have the back wheels a foot or so in the air...
If you build a cart to do this if you make the cart about 1" higher than the stock height of whatever you want to set the cart on you won't need to raise the rear wheels...
Downside is you have to be small enough to get in and secure the trans crossmember first which for a big guy would be difficult the way I do it...
This way is probably more "work"...
But everything is much easier to make it nice without scratching anything up...
The upside is any suspension parts that need replaced can all be done at the same time...
