I would recommend filing in small claims court. That way you'll either get a judgement against him if he fails to show, or if he does show, he'll have to explain himself to the judge. Once a judgement is made, you can place a lein on his property or issue an information subpoena which will provide you all his asset information and allow you to collect the value of the parts.
If I have some free time, I will see what info I can dig up on him as well. For some odd reason I feel I've looked for him before.

Heres his home address and a phone number for it...
