My waterpump was new when the back in 2008 when I had the cam chain and gears renewed, or 2009 when the engine was rebuilt by DickP. In anycase its about 10 years and 30K miles. So I thought I'd look for a source of the Cardone 21118H waterpump north of the border since they seem to be backordered in the USA.
From the Cardone website I found a couple of sources in Ontario and contacted the closest one. I got this response back from them:
"Regarding the water pump. Cardone does not have any stock in any of their warehouses. I am able to supply you with a new hi flow water pump from GMB (130-1260P). I confirmed with their tech department this morning that it has the roller bearings that you requested."
He provided a link to the product at:

GMB says they are a 75 year old company manufacturing OEM and aftermarket auto parts. The website for GMB is
https://www.gmb.net/
From there a search on GMB for a 1976 Toronado water pump comes up with 3 models for AC vehicles. An OEM (cast iron), an aluminum version and the recommended 130-1250P an HD version which by its weight also seems to be aluminum. Looking at the application list for this pump it shows 1980-71 Toronado All Models along with the 5.7L 81-84. Does this seem to be the correct pump for our application with the correct turning direction?
They do have a PDF on Heavy Duty water pumps with a construction cut-way showing roller bearings, but no listing for the 130-1260P. Only industrial and trucks are shown. However they may use the same shaft construction on all pumps.
So I'm wondering if this GMB company is making these and supplying them to Cardone and this "Epicor" companies to distribution to the auto retailers. Would this knowledge help to increase the availability of the desired pump?
Opinions?

FWIW, I've had good experience with GMB parts in the past.... I would not consider them up to full OEM quality, at least on the surface... (castings aren't super nice, non-critical surface machining is not as good as an OEM part) but I do consider them a solid aftermarket replacement. The parts that need to be well machined are... And based on the fact that I've never had an issue with using their parts, I would assume under the skin, the parts are also of adequate quality.
Also with a grain of salt, I would put Cardone on the same level as GMB so far as quality.
Interestingly, if you buy the Flow Kooler pump that Jim K. sells, it will be made with a GMB casting. (at least mine was) When the issues with the water pump bearing failures occurred, I reached out to Flow Kooler (as I had one of their pumps already installed on my engine) and they also stated that their pump uses roller bearings on the snout. When I asked them about the GMB stamp on the casting, they told me they purchase the castings from GMB, and then add their own in-house designed impeller.
Based on your findings, I would assume Flow Kooler uses the HD GMB part you mention.

I put a GMB heavy duty water pump on my new engine rebuild last year that I got from my local premium parts house (Merle's, now part of NAPA). After almost a year and 4,000 miles, it has performed just fine, but I obviously can't speak to the long term durability of the part.
On a side note, when I first filled the engine up with coolant, the seal on the pump leaked. I was freaked out and concerned about this, but the leak stopped in short order after the initial engine run-in, so I'm guessing the seal (ceramic, maybe?) needed a slight wear-in period. No issues since.
