we seem to fried a few MSD ignition modules with Tiggr, and it seems to be tach related.

Brad was gonna ID the tach I should buy from Summit that fits right in the dash ('73).

But he's off-planet.

Anyone else know what I need?

Autometer "monster" 5" tach.. you need to put a little tape or rubber around the back so it friction fits into the hole. Works good though. You don't need the shiftlight or mounting stuff.

ps. Like this (big picture): http://www.Earlyapex.net/images/driverside.jpg

I think this is the one I have: http://store.summitracing.com/partdetail.a...rt=ATM%2D233903

yepp, got this info off the kragen web-site ...

Autometer 6811
Tachometer: Pro-Comp; 11000 RPM Memory Tach; Operates On Standard/Electronic Racing Ignitions Like MSD; For Accel BEI Laser I or II Ignitions Use 5215 Adapter; 5"

Or you can have NH Speedo or Palo Alto Speedo gut your tach and put new guts inside to work with your electronic signal from the MSD.

I think around $150 or so.

thanx much!
