We owned Dave Wren's '63 Plymouth wedge car back in 1968-1971. Sold it to a Fellow by the name of Jim Isherwood who now campaigns a '67 Belvedere SS car out of Mission BC.Jim sold it back to Dave quite some time ago. I know Jim keeps in constant contact with Dave and when I talked to Jim a little while back, Dave still was kicking and still had a pile of Mopars on his spread.
Around Missoula Montana I beleive.
Don't have contact info for Jim, but someone on this board from the North west should know him if you want some info!
