Hi Bryan, this is the part number I used...#42125...a 17.5 mm long insert, used on the kit I pruchashed....#4121...as shown on the Timesert catalogue page...
http://www.timesert.com/html/sparkplug.html should give you the exact page I am looking at just now.
I did order the long ones on purpose, as I indicated previously, I removed the little excess beyond the plug hole in side of the chamber with a Dremell tool, very carefully so as to not leave any detonation hot spots from pointed marks.
I felt I would go to the manufacturer to get my kit and inserts as they knew most about their product.
Let me know if you decide to borrow my kit.
Joe :D
