Yup, that is also something I have thought of doing.  I do have a spare 
cheapo tach that I bought to check against the Smith one.  Once I get the 
Smith out and see what it looks like inside I just might try a internal 
swap.  I would like to stick with a original, but we'll see what works out 
the best.

tnx
George
