Stop in for a cup of coffee

We did get the kid's 71 Valiant started a week ago...

But we lost the gear detents in the trans and can't get it in park. need to get a trans guy to look at it if I can find a good local guy... We have to jack up the rear tires to run it, and I don't want the wheels spinning during the cam break in. or revving it... Don't want the wheels spinning too fast in free state...
