Blackburns Original racks were 8mm/1/4" solid aluminum rod .. if I were taking it on, the whole (4th picture) current mounting system would be removed

in favor of one from (example) Klick-Fix .. Rixen and Kaul supply hardware to many bag makers .

a set of DIY hooks can be made from aluminum metal, for cheap at the Hardware store

Straps with cinch buckles wont let the bags bounce off like springs and bungees have .


I guess the thing on top in the middle is a catch to keep it on.

Good Luck ..
