Sparkplug insulator question?
 

Hello all, I'm have a 1977 911S. One of the brown Bakelite insulators cracked. When I received my much awaited PP box, the new one was different. The old style had a pointed probe where the wire meets. The new one is just flush. Will this be compatible? thanks Roger

If I understand you correctly, the spark plug connectors have different connections to the spark plug wire. Your old connector has a wood screw type connection, and the new connector has a machine screw connection which requires another piece to be crimped onto the wire to make the attachment. In short, the new connector will be compatible once you get the piece you need to attach it but it will not screw on straight to the wire like your old connector.

Thanks ossiblue. The old connector had the wood/machine screw. The new connector has no screw type insert. The 90 degree wire accept innards are flush with a small hole leading to the sparkplug body. Roger

Yep, that's it. You may wish to contact Pelican for either the piece that crimps on (I think it's available--it has a male thread end that fits into the plug connector) or replace/exchange the new connector with the wood screw type.

Postscript,
The spark plug connector indeed was suppose to have metal screw type fastener. PP graciously sent a new one, while providing return label so they can inspect the defective part. Thanks ossiblue and PP for all the help. You both are why I'm here. Roger
