steering box rebuild, need a worm shaft...

sent my steering ( 67 16:1) box out to a local rebuild shop, and it needs a worm shaft, anyone know of a supplier/rebuilder that might have one?
 
I have a box full of parts with a disassembled steering gearbox that looks great (no obvious wear). I don't have the tag though so I don't know what it's from. I think a 68 (short shaft) without PS so probably the wrong ratio. Do you know how many teeth or another way to tell? Which part do you need? The sector shaft (vertical in pic), rack block or input shaft (horizontal in pic)?

just spoke to my re-builder and it is the input shaft, he says 67 & 68 will be the same. mine is without PS, let me know if I can buy it from you.
 
Good thing. Cause I looked this up for ya yesterday and I was getting a little worried for ya.

Gary, this is a bit more work... but I just disassembled a spear-O-matic gear box. It's the one piece, like 4 foot long input shaft. I am using the upper portion of the shaft for my rat's steering shaft, but will be cutting off the lower worm gear portion. The box was very tight, no slop.

You can have the remainder of the lower worm shaft.... you would just have to get the end cut down and splined... something not real cheap unless you can machine it yourself.

Just throwing it out there if worse comes to worse.

That's great! but now I'm second guessing myself on the ratio, non power is 19:1, power is 16:1 unless it's a shelby, then non power is 16:1, what about a non power GT, is that 19:1? just googled it and it's 16:1 on the GT. crap

Let me call the re-builder and count teeth just as you suggested. how many teeth are on yours?

Thanks Jeremy, let me see how we make out with finding one that doesn't need machined, do you know the ratio?

I'm sorry, I don't. I just know it was a manual box, 5 turns lock to lock.

I will check it out when I get home
 
Okay, it's the worm shaft assembly that creates the ratio, if I take Craigs it will become 19:1, which might not be a bad idea being it's a big block manual steering, my coupe is a small block 16:1 and it's armstrong parking, I've never driven a 19:1 standard steering.... thoughts??
