Yes, Glen is right! Two good solid 2 X 4 have worked great for our fam
ily for years. And have someone on the outside watch your car as you drive it
up the ramps to make sure nothing catches or scrapes. Also, I cut a small bloc
k off a 2 X 4 and used it as a floor jack cushon.....works great and protects
the underside of your car! It's cheap and effective.
