Sorry to hear the news Helmut..
If you sent the $ across the border by mail it might be considered Mail-Fraud so may be worth telling him this?.
Do you have his Phone # and if so do you know if the *67 feature before dialing him works across the border to block your #?.
Googling shows the below...same # in other car part ads plus he advertised a couple 12Bolts on RacingJunk too...
