NOS ignition pickup coil - how bad do you want it?

[LAB3]

If you remove the 3 screws with the pick-up coils on it and just replace that part, then the bolts do not need to be drilled.

Yeah, that was my thinking too.

Did you need to use a bolt extractor to remove the old bolt shaft? Was there enough material to grab with vice-grips and unscrew the tamper bolt out?

I used a drill to remove the heads of the tamper proof bolts and then removed them by hand.

Thanks speedlimit85, that does not sound too bad.

Nice shoulder bolt. M8 X 1.25 threads?

[DEEBS11]

I found that a 78 has a conventional pan head screw (they must have changed due to dealership warranty issues of customer tampering) part # 97885-06030-00. The middle of the part number states it's a M6 x 30mm length. I'm guessing the thread is 1.25mm.

Here is a picture of a 1980 anti-tamper screw. It looks like an M6. Part # 3H5-81674-00-00.

The thread pitch on those is 1.0

Thank you Phil.

Yep, I used a gauge to double check.
