While they are becoming fewer and harder to find, look for a mech who specializes in older cars. If he can work on a flathead chevy or ford, he can work on your kaiser. Just be sure to lend him your shop manual when you have him do some work for you. If/when you find one, check on his bonafides...BBB, online reviews, etc. Ask if he can provide customer references. If he can, chances are he's the real deal and not some fly by night...
