Update:
I've been in a private conversation on this web site with--and deeply indebted to--
Robert Smith, who has the same NAPA-branded top chest and mobile cart as I've posted about previously.
He's determined that these NAPA lower boxes were made by
Waterloo starting in the late-1980s as Waterloo model number 50710SS "Mobile Tool Cart" (I'd have called it a "Roll Cabinet) in the "Magnum Plus" series. Even sent a Waterloo catalog page (attached) proving their origin. The 50813SS "13 drawer top chest" must have been a later addition to the Magnum Plus line. I have NO idea what the NAPA model numbers were.
We each (separately) contacted Accuride "Help Desk",
https://accuride.zendesk.com/auth/v2/login/signin?return_to=https://accuride.zendesk.com/hc/en-us/requests/176859&theme=hc&locale=en-us&brand_id=114095259434&auth_origin=114095259434,false,true
and communicated with Jorge Perez. Each of us got full sets of replacement plastic and felt pieces to rebuild the 48 drawer slides. (The extra-wide bottom drawer has double slides--two per side.) There are FIVE part numbers needed. I received the first three, and had to request the last two separately. Robert, I guess, got all five items at the same time:
One plastic
Detent Bumper per slide, 2327-2663-YE
Two plastic
Dog Bone Bumpers per slide, 2327-2959-YE
One
Felt Pad per slide, 2307-2502-YE
One plastic
Silenced Outstop Bumper per slide, 2327-2792-YE
One plastic
Outstop Bumper per slide, 2327-2672-YE
I received extra pieces from Accuride. They sent more pieces than I needed for 48 slides.

Robert removed all of the slides from his box. Requires drilling one rivet per slide. He says "the rivet is a
5/32" x 3/8" steel rivet. Stainless steel rivets are cheap on Amazon, 100 for about $10." I found that to be true. There's 48 slides on these top-and-bottom combination tool boxes, so 48 sets of replacement plastic and felt pieces, 48 rivets required.
I have NOT removed all the slides from the boxes; I've drilled TWO rivets to remove TWO drawer slides--trading a bent slide on a "main" drawer for a straight slide from a "small" drawer I don't use much. I have not installed the
Silenced Outstop Bumpers or
Outstop Bumpers (Yet. Despite Robert's best efforts, I'm too stupid to figure out how they fit in my slides--there is
not one remaining outstop bumper or silenced outstop bumper in any of my slides.) The other items--the
Detent Bumpers, the two
Dog Bone Bumpers, and the
Felt Pads are dead-simple to install, but require the drawers to be removed (but not the slides from the cabinet). And the ball bearings and races are in desperate need of cleaning and re-lubing.
I had to clean a million plastic bits out of the bottom of each box. The original plastic slide pieces basically disintegrated into chunks and pieces.
Accuride suggests white grease for lube. I am going against that recommendation, using JB-80 aerosol liquid lube because I think "grease" just catches and traps dirt and debris. Some but not all of the drawers have a "lip" on each side, acting as an umbrella to shield the bearing races from debris. Even so, the races were hatefully filled with garf and garfelderfarb.
Robert's boxes have different drawer slides. He's got "light-duty" slides, and "heavy duty" slides, but all of his have have fewer ball-bearings in the mechanism. There's patterns, his slides have a certain number of ball bearings, then a 3-bearing gap, then more bearings, then another 3-bearing gap, then more bearings.
All of my drawer slides are identical aside from Left and Right. Mine have full sets of bearings with no gaps. We don't know why his box has different slides from mine.
My drawer slides:
His light-duty drawer slides have only two rows of visible ball bearings, the others are "hidden". His "heavy-duty" drawer slides have the four rows of visible bearings like mine, but with fewer balls.
Three of my drawer slides are bent and should be replaced. This is a matter of "abuse" via "accident", so not a warranty issue. I'm hoping to buy two pair of slides. I inquired with Jorge, and got zero response. I guess I need to contact the "sales" people at Accuride. I note that Accuride does not list "tool boxes" on their web-site. I'm concerned that they're going to consider these "proprietary" and make me get them through Waterloo. But I haven't actually contacted the sales folks, so maybe I'm just being paranoid.
There's no use talking to "Waterloo" about this.
As of July 28, 2017, Waterloo was purchased (and subsequently destroyed) by Stanley Black and Decker. Rat bastages.
