I think I may have this sorted out now with regards to the bungs. EGT sensor doesn't need to be moved. Just need to add the two oxygen sensor bungs right after the secondary (now primary) cats. Losts of pics here on this forum.
J Style O2 Sensor and the fitting is M18 x 1.50 thread and 304 stainless steel.
Checking with JRP locally here in Canada. Apparently Verocious Motorsports in the states will be my next option if JRP doesn't come through.
Still need to sort out how many clips are required for the o2 sensor cable relocate.
I see four here from another member's super clean install.
Thanks to all of you that replied directly. When I get around to doing this installation, I will take more pictures and post them all up.
