I've had a fifty four five window since 1979. My first vehicle. In 1982 it broke a couple of rings and has been parked ever since. Recently I picked up a 235 out of a fire truck. I have started the install and restoration. Got a question about the new motor though. It has a strange number next to the distributor. S0405XH ? I'm looking forward to this overdue project and this fourm has already been very helpful.
