SWR Goliath I - what to do with?

I have an old Goliath, and it's too big and heavy for what I need it. Horn blew a long while ago, and it's just not in good shape. I'd like to chop it and make it a 2x10 4ohm cabinet but I am not sure where to even start researching where to go with it, and am I going to invest more into making it usable than simply going out and buying a new cab. I fear it's the latter, but would like to avoid just shoving the cab into a landfill . . . I would sell but honestly not only would no one want it . . . but after my cat used it for a litter box . . . I really don't need the negative feedback.

thanks!
