1966 3 speed manual trans problem. Help!

I had a 68 chevy pickup with worn out linkage. It was a challenge to drive,especially if you never drove it before,worked like a theft deterrent.
I was going somewhere with this- oh ya
If it is worn linkage, sometimes the problem moves with the adjustment, as by getting 1st to work you lose reverse.
I was thinking the same thing! Reverse, 2nd and 3rd work so good I'm hoping for the best! I brought this car back to life so far and it has been a pleasure mostly because it was simple things and neglect of the previous owner/owners. Thanks for your help!
