type 89 speedo data information?

[CHRIS & CAMILLE PERRY]

This is exactly how mine busted as well (missing teeth).  I found an outfit 
somewhere in teh east that would sell the gear...for somewhere around 
20.00... but I ended up buying a complete guage set from Chris Semple so I 
still have my old Speedometer as well.  I will try to find the contact info 
for the place was going to get it.
