Thanks for the replies.This car,seems to have been built for the vice-president of Chrysler Canada (no longer exists) Moncton New Brunswick.It was shipped out to LaSalle autos Quebec,Canada(can,t find any records of it) I have record showing it was Ziebarted on Oct 23/70 and registered to a Georges Blake 3 days later(oct 26/70) in Quebec.No private person could have undercoated it before registering in their name unless they were in direct association with Dodge America.It was then sent to Moncton and received by Norm Macklem VP of Chrysler for him to show clients the Challenger line.Norm sold it to his son Terry,who sold it to a friend Boyd Anderson (city counselor) who upgraded the 318 to a 340 with 360 j heads (what does the J stand for?) Have a picture of the car qualifying for a race with the # 68 on the side.I bought it from him in 1975 I drove it 1 winter and noticed the Ziebarting had rusted the vehicle bad enough that I parked it in 76 in my old garage and it stayed there til 8 or 9 yrs ago when I was able to afford a frame up restoration.I paid for the bodywork but had to assemle it myself.(I'm sure I messed up here and there,but have been driving it for the last 4 summers.And now you know the rest of the story
