Technical please help with steering column identification

so I got this '29 model a pick up that supposedly was built years ago then put into long term storage before the builder died. I was told he had a sbc and 4 speed in it but as you can see in the pictures im changing that up. Anyways long story short I have been going through and trying to figure out what parts he used and now im down to figuring out the column. its a tilt column thats non collapsible with a weird cable operated switch mounted down low on the column itself. Its hooked to a 67-73 mustang box but doesnt look like its a mustang going by google image searches. any ideas?

 

Early 60's GM tilt. Hard to find parts for. Tilt lever makes me think Olds are Buick.

 

64 Chevy?

 

It does look GM, but if the key switch is in the column that would be 1969 first year.

 

Looks similar to the '64 Buick tilt column I have. Same switch setup.
I have a wiring diagram for it somewhere...

 

one thing for sure, if it is GM from the 60's it is worth a bunch of money to the guy who has a car that it came from.

 

i think I just found the switch, it looks like '63-'65 gm like a couple of you said. RMR&C, I would love to see that wiring diagram! Thanks Guys!

yep thats the switch, they cut off the other switch with the purple and green wires. any idea what that switch is?

 

I believe it is for back up lights and neutral safety, Used with a column shift.

 

Yep, that circular one is the NSS. And You need one someplace on the car.

Ppl wires for starter green for Reverse lights

 

You don't need any stinking safety switch!

 

ouch!
