REZARF- Those inserts are called "nutsert" got them in a local nuts and bolts specialist in Glendale Az-"Mark's nuts and bolts" they are somewhat hard to get at that size in your local hardware store, however I think macmaster-carr
may carry them as well -if you have hard time to get them I'll be happy to assist. they are kind of a pain to install- the make a special tool for them but it's very expensive.
the idea is to collapse the bottom into the drilled hole for it to hold tight. we finally worked a power steering pump pulley installer to do the job.hold great!!
AFSOC- I'm not sure of the tool chest model but they are identical boxes side by side-yes the have some years on them and Snap On dealer just replace all the drawer slides
for free-it's the proverbial "you get what you pay for"
