Just started 66 barracuda- No Drive, No Reverse

Hey guys, I bought a 66 Barracuda a while back and have been mostly concerned with getting the engine running. Today I decided to see if it would drive around the parking lot so I put it into gear and it didn't budge. The previous owner installed a shift kit (it was originally a steering column shift) It will go into reverse and neutral and drive but it wont move and then when I put it back into park it will grind a little bit. It also has no kickdown linkage. How should I proceed here? All of my experience with with manual trans motorcycles.

I think what I'm going to do first is watch the B&M installation videos so I can see if it's been installed correctly.
