Might be worth while looking for a match at the junk yard or buying a car, blown motor etc. that would have the guts you are looking for.
Drives me crazy when people commit these random senseless acts, it's always people who take no pride in their stuff who ruin other people's stuff.
A buddy had two radios stolen out of his car. Smashed window twice. Installed a third new radio and taped razor blades to the back side of the new radio. Went to his car one day, window was smashed again, but radio was still there along with bits of theif's fingers.
