Those radius rods are pretty flimsy,as Rotorwrench says.They have seams,and are not welded the length of the seams.When they bend,they go quick.One minute the car is sitting on them,the next the car is sitting on the runningboards.Also,the radius rods are angled up,and the lift pads slide right up and squirt sideways with weight on them.I have 10 inch posts,the fronts go right at the side motor mounts,and the rears go under the frame right ahead of where the radius rods cross under it.I have an old inground lift that was installed in a Ford Garage in 1930.It has two four inch I beams,12 feet long,you just drove the car over it and pulled the lever.It picked up under the axles.I got it from the old Ford garage,the owner had worked on VW's for 35 years,it worked on them just like an A.I dug it up and never set it up.It's just too much work to set it up to save 10 minutes to pick up an A on my two post.
