Steering pull at Highway speeds

[Otsa580]

I am preparing my 69 blazer for a 4 hour drive to my new house. It has been sitting for a while now and I need to do some work to make sure it will be safe to drive. I remember that there was a lot of play in the steering going 60+ mph. I am guessing that it needs an alignment and maybe new tires. Its a 4 wheel drive with 31 inch tires.

Anyone have any ideas on common parts that need replacing or worked on.

I might trailer it home but I think it would be a lot more fun to drive!
