OK Tim, you mention that the electric motor does not work with the original radio. WHY? I am running into that issue but want to compare notes. Are you referring to the wiper linkage? I bought the electric wiper conversion and installed. Then the radio going in, interferes with the wiper link to the passenger side by at least 1/2". Is this the same as what you are talking about? Is there a solution?
I'm asking because I also didn't see this coming and I repaired the radio and would like to reuse. So, I'm looking for someone that has experienced this.....
