Chad the hoist is self supporting on the floor the foot you can see in the picture extends 4 feet from the post . It is lagged in place but does not depend on the bolts in concrete. I do put a jackstand under on the far side when I'm working underneath.
Dave nice to see you got the Mustang out. I like trains but not a big fan of the old Plymouths ---Trevor ps I think the Savvy was a US only model
