But wait; more box truck saga

This will seem rather incidental, until you recall stabbings by frayed steel cable.

Same ramp, that I've found remedies for other negative conditions, my wounded thumb tipping scale of project votes by one. Actually it was a tie, but I capitulated, for his suffering.
You couldn't avoid it and set the loop over the anchor. Purpose is to not foul descent of platform by ramp hanging straight down. Age of course has misshaped and worsened it. Also, equally important, it keeps rolling carts on the platform when raised, being in near-vertical position.

So cable had to go. A 1/2" thick pad, drilled 5/16" on center holds it in place, with a swaged terminal. Other end is a loop, in a worn plastic jacket, wires poking through. Not a fan of cable, but decent substitutes are limited by the thin pad, not compliant with normal hardware.

The workaround fabbed bridge for a cut link,

sectioned from rectangular tubing .18 x 2" x 3", a length of chain, and a small flat plate of hot-roll for the 'eye'. (In the morning, will check chain with other pitch sizes to get closer length needed and convenient attachment) Same 'eye' plate is unfinished on one end for adjustment of final length.

Halfway through, realized as I manipulated tools, "hey, this could double as a tray, a work table!" There's only 1-3/4" difference in radius from the 90° position to incline they designed, piece of cake!

The hook location is that length from its center to the 'eye', again 1-3/4".

As with certain DIY, it's good to hedge problems by not shaving everything off until it's clear the alterations work. For this truck to roll, that gate would be a roadblock, if unsecured.
