You should check AliExpress for those. You might be able to find some knock-offs. AE is actually really good for things like this. The other place to check is Ebay, in case someone is selling NOS (new old stock).
I’ve tried both. They don’t make 8spd era hoods they do have some 9spd clones. NOS has n’t existed for years and when it comes up people ask $100 for a set of hoods.
I wonder if any of the companies making 9spd clones would be interested in making 8spd clones. It might not be worth it for them, but probably wouldn't hurt to ask, especially if people are actually getting $100 for a set when they dig up some NOS.
