Need Help Finding Front Derailleur for '98 Beast

[TIM0THY]

Hi guys. New member here. I've owned what I believe is a '98 Beast since 2002. It's time for a new front derailleur. Can someone here point me in the right direction, as far as which derailleurs will work with this bike? Thanks.

Edit: I'm particularly wondering about the tube diameter. Also, I swapped the original shifters (LXs, I think) for some Grip shifters from the same era. They seem to have more tension than the original shifters and pull on the derailleur more than the originals.
