I was looking through a catalog and I ran across this relay which looks really close to the ITT relay. The measurements are fairly close and it is only $9.30.http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&pa=139766CK&productId=139766
That definitely looks like a suitable replacement/substitute. Good find.
