I was contacted by a '58 Plymouth owner via our website today who has
a 200 mph speedo in it. He also included a photo. He didn't tell me
what model he had. Anyone ever heard of this application? Was it in
'57s as well? Maybe it was a police application? Canada didn't
go metric until about '76, so wouldn't think it was in kms. I imagine the
55-58 Chrysler parts book would list it, but my book is down at the shop.
