Missing ABS Jake Hujoo Part

[Plague]

So after about a year, I finally have some funds to start reworking a custom I was working on with a Hujoo Jake doll. I had him in pieces because I was spraying his whole body at the time, and uh, well, I took meticulous care to be sure all the pieces were still where they belonged all this time. The tiniest pieces are still right where I left them. Buuuuut I'm now missing a foot, and have no idea how.

I don't want to spend upwards of $50 (because of shipping) on a whole new doll for one foot. Does anyone have any ideas on where I can find individual parts? What kinds of clay can be sculpted and spray painted with ABS plastic that will hold the same color and not look slightly off? Maybe I'll just craft my own. OTL
