I am going to upgrade the engine in my mk II restoration project with a 1275. When I do it I also want to go to an alternator which means I will lose the tach drive. I know a lot of you have done these conversions. What have you used for a tach. I would like to find something that looks close to original.

Frank C has taken the guts out of the mechanical tach, popped the needle off, saved the faceplate, and put an electronic tach back in the same case, reinstall pointer needle. Only you know the difference. Give it a little bit and someone will post the How To Do It step by step.

Hey I found it first. From my stuff I've saved series.
Electric Tachometer Face Swap for Bugeye
BUGEYE TACHOMETER CONVERSION
Many Bugeye owners are confronted with the problem of sorting out a tach drive once they have converted either to an alternator or discover that they cannot find a mechanical tach drive at a reasonable price. Frank Clarici offers a great piece of advice on how to convert an electronic tack over to negative ground. I have taken his advice one step further. Many Bugeye owners do not want to give up the stock look of the original gauges, so I have outlined here how to solve the tach drive as well as the stock looking gauges problem.
You will need:
• original Bugeye tach
• tach from a Mk3 Sprite or Mk2 Midget (this is an electric tach, the same diameter as the Bugeye)
• Frank Clarici instructions on how to convert to negative ground (if your car is negative ground)
• Small standard screwdriver
• touch up paint (optional)
1 Hour labor Procedure:
• Remove the front chrome ring, glass and seals from both tachometers by twisting the ring. The rubber seal on them may need to be replaced.
• Very carefully remove the RPM indicator needle from each of the tachs by pulling straight off the post.
• Using a small screwdriver remove the 2 small screws that hold the face plate of each tach.
• The screw spacing is different for the faceplates, lay the Mk3 faceplate over the Bugeye face plate and using a small drill bit, drill the 2 holes in the proper location. Be very careful how much pressure you put on the faceplates as they are very soft and can be deformed.
• (OPTIONAL) Use super glue to affix a thin patch to the backside of the faceplate or fill the hole with epoxy, to cosmetically close and paint the old screw holes in the Bugeye faceplate.
• Install the Bugeye faceplate and RPM needle onto the electronic tachometer.
• Reinstall the tach chrome ring and glass with new rubber seal if needed.
• Install reconfigured tach into car dash and do electrical hook up. You will connect a 12 volt line to the spade connector on the rear, the case is grounded and a length of wire will go from the coil, loop around the sensor pickup on the rear of the tach, and back to the points terminal on the distributor.
It is that easy, drop me a line if you need more information,
