Tach replacements

V35B Bonanza SN D9359  We are currently looking for a coil pick up for the tach.  Sends info from  mag to tach.  We have old style vert tach part number for coil pick up is 96-389002-1.  Would you be able to guide us in right direction to buy one?  We have check everywhere and are coming up with no luck.

Mike;
 
That pick up is apparently no longer available.  I checked to see if Bendix (TCM Ignition) had a replacement, but no.
 
A search through the Bonanza kit directory found a solution, and, I don't think you're going to like it. 
 
Raytheon Kit No. 36-3002-1M, replaces the vertical instruments with round ones for your airplane.  RAPID's web site says available in December, with a price of $12.5K.
 
My suggestion:  Panel space available, go with a Horizon digital tach; nice units.
 
Gear Green,
Mike
