Thank you
I've seen them anywhere from 48" to 55" wide and many racing sanctions/tracks limit width to 48" so I figured that would be a good starting width. Similar mounting is normal, but solid bar stock seems overkill and heavy, but you use what's handy. I hadn't figured in ramps, but don't want to lift anything that awkward or heavy either, So I'll add ramp materials to the list. I think I remember seeing pic's of the underside of the lift, but thanks for those.
