Check igniton switch and neutral safety switch. 69's used an interlock switch on the steering column to disable starter except when in reverse, I think.
They used a switch on the column same as an automatic used.
Any of these switches can fail partially and cause the starter solenoid to work poorly.
Try a remote starter switch on the starter to test. If the remote switch works, you have a problem with wiring or switches.
I know you have a 67, but others with 69's may read this.
If all your connections are good, and you have a good ground, then I would say to try another known good battery, as the one you have may have a shorted cell, and thus only enough to kick the engine over once,as you say. also try a search in this section and maybe more answers can be had. GOOD LUCK.
