[DW31S]

I'd say the talk with the original owner will answer a lot of questions, especially the radio. My '69 W-31 is similar to Ryan's car in several ways and was ordered without the radio and corresponding equipment. There is a continuing debate over the term "radio delete" as these cars had NO radio as standard equipment. The first owner of my car (sold in Feb. '71 after it's racing days) wanted a radio, so an Am was installed along with an antenna. Yes, they drilled the hole in the fender WAY back in 1971.....funny thing about mine?!? the owner's name is written on the radio!
I can believe Ryan's car could have come without a radio, if it, too was intended to race.
