Since those screws only keep the adaptor from rotating, I'd wash down the area with mineral spirits to get any oil out of there and JB weld the adaptor in.
Hmm... the adapter is going to require some pressing or hammering to get all the way in. I have no experience with JB weld (despite maintaining an Airhead BMW for many years). Does it take a while to set up? That is, if I use it will I still have time to press in the adapters?
In general I'm a bit leery of using anything glue-like be it green locktite or JB Weld or whatver on a bike, but I'm grateful for the suggestion and at this point I'm certainly not ruling anything out.
