1964 a833 hard to get into first gear

I had to read it twice. Sounds like it needs less free play. (more clutch
I'm not following you.

If clutch was not releasing enough when he pressed the pedal down then it would be hard to get it into any gear, correct?

If the car is moving, then down shifting with a tight clutch would be doable.

And if the engine is off, and the car was sitting still it would shift no problem clutch in or out

What am I missing.

I just reread you post...

I think we are saying the same thing...

Less Freeplay = more clutch disengagement
