Is there a way for me to recreate the wallet.dat files in order to import them into Clam-Qt so that I can claim my allocated clams? Any advice/guidance/clues would be appreciated.
Yes. Run bitcoin core, go to the debug console, and type
importprivkey "" false
for each privkey you have. Then quit bitcoin core and the wallet.dat will be ready to import into the CLAM client.
Alternatively, use just-dice.com's chat tab. You can "/dig " to check an address for CLAMs, and "/dig " to dig the CLAMs up, free of charge. The CLAMs will be credited to your Just-Dice account, from where you can withdraw them to an exchange of your choice, or to your local wallet.
