Just did some reading on Hi-Lift, this may be old news but it's from the Sema show.
I see they have a neoprene sock for the jacks working parts, to keep all the junk out while stored.
Also a new mount system that attaches to round tube bumpers, roll bars roof racks etc. made of alum. and SS, with knob/wing turns. Will also fit some square stock.
I have a new mod worked out already for this, just need to check on a price.
