SM420 Question HELP!!!

Guys,
I've got an SM420 mounted to my 261, ready to be installed onto my '59 truck frame.
I have a problem and need some help.
The teeth on the speedometer pinion are worn so badly in one spot, I need to replace it.
I thought, no problem, I'll find one on Ebay.
What IS a problem is that my pinion has 13 teeth and I can't find one like it.
There is a pinion and gear set on Ebay that is a 5-19 tooth arrangement.
The question is, will this work in my tranny? Can I just pull out the gear ring from the yoke that matched my pinion and put in a different set?
I hope this is clear enough to understand... sheesh.
Any help is appreciated!
Jerry

I think the 13 tooth is the one used with the 1/2 ton versions.... harder to find...

Which puts me back at the question, will the 5-19 tooth set swap out and work?
