Looks like cardone will rebuild it for you if you have one to send that is.
Yeah I’m not really sure on that your probably correct. I did see that caprice, bel air and biscayne had the same motor in those years but not much of a help lol it’s looking like send it out, find a local rebuilder or Hubbard’s or bobs but they want $300.00That picture is a single speed..no wipers. I think Impalas had 2-speed from the factory.
My 65 Impala has a one speed with no washers looks to be original
WOW, you guys are great! Thanks for all the info. I had found that Cardone will rebuild and that some of the specialty suppliers have new reproduction units priced accordingly. It seems that the 65 and 66 are the same but unique from other years. I hope to find a working used unit and will check the leads provided. Thank you very much.
