Yeah, Gint, I think you're right about the shipping. They are not light either.
The boxes are 22.5 inches tall......using the casters and about 17 inches square......they work on their sides also.
I use a regular floor jack with about 12-14 inches of lift. I have a pile of hay (2 X 12 & 4 X 12s blocking). So, up with the jack then use the hay to block up the car.
Down with the jack and more hay( 6-10 inches worth)gets loaded on the jack pad & up we go again & block the car up higher...more hay. Repeat as necessary till the blocks go in sideways....then more hay on the jack & up again ..if you need the height....like when I was pulling the motor...prolly 5-6 times over the years....all by meself. It takes about an hour a litttle sweat to get it up to full height.....but I'm old.
Anybody that buys em' will get enough hay.
It got so I could pull the motor in 6-8 hours by my self from the start to finish....a bit less time to reinstall.
I never liked to be dependent on anyone to help with that job but when I had help it was apprecaited.
