Thanks Rex! I contacted Workhorse Products in the meantime, and they gave me a link to where I can buy their platens. Apparently, Chaparral Industries just changed their name to Workhorse. Their current press designs are not at all like Chaparral presses, but the brackets are the same size.
I checked screenprinting.com (top result in a search for Ryonet) and Action Engineering, and their pallets cost quite a bit more than Workhorse ($170 - $180 versus $120 from Workhorse). Here's the link if you're interested:

Thanks for the input... I hadn't considered the thickness of the pallets when I ordered them, but I never had any trouble with the ones on the last Chaparral press that I used back in the day, so it never really occurred to me that there might be an issue.My 4/1 Odyssey has thinner aluminum platens. It warped from the constant flashing. I only had it 4-6 months. I now have a M&R manual and the platens are much thicker as well as that aluminum grade is higher. I also have action engineering platens and the are slightly thicker then the platens are much heavier then the M&R so I would say it’s a higher grade aluminum yet. Also there are honey comb aluminum platens and that’s what the workhorse odyssey may have had and are know for warping. If they are limit your flashing times or run a fan as a cooling station
Not all aluminum platens are created equally.
