I was at bow wow ( i know!! ) on my way back from wrk, and asked about a upper column bearing for my 79 bus, but they have never carried them. Does airspeed have this bearing, or would i have to pull one or order from down south? and has any one replaced one of these; apparently they don't fail very often. Just wondering about pitfalls to watch for. The previous owner rear ended someone and mine has about 1/4 inch play now. Thanks for the input
