Stop in for a cup of coffee

Good morning all. Might look at the 67 some today. Strange it has no park. So as you might know, my car trailer is a roll back. Tilt deck. So I load car on backwards because of how I will have to unload it with no brakes. To keep the front facing out. Well, I winch it on my trailer, to where I want it, put it in park, there is no emergency brake. Part of the failed brake conversion. Then put deck back down. Next thing I know BANG!! WTF? I look, the car has rolled forward and the rear bumper has hit my tail gate, leaving a small dent!! Ouch!! That is how I found out the park does not engage!!! Another battle scar on my truck...
Damn!
