How to torque LNE IMS nut
The LNE IMS bearing has a 12 point 11mm nut instead of the factory 13mm nut therefore the Porshe special tool I purchased to torque the nut will not work.
I have not found any commercially available torque wrench adapter that is suitable to reach the nut recessed within the IMS flange. I don't know why they couldn't source a 13mm nut instead of a 11mm.
Anyway, so how has everyone who has installed the LNE IMS torqued the center nut while holding the stud stationary with a screwdriver? What kind of torque wrench adapter did you use and where did you get it?

For the record: Snugly tightening the nut first with a box-end wrench and screwdriver will prevent the stud from turning when you torque the nut with your torque wrench.

The fastener in question is referred to as a "jet nut" and is an aerospace quality, completely flat based nut thats far superior to anything from the factory.
No special sockets or adaptors are necessary, just a 12 pt 11mm or even a 7/16" box end wrench or socket will fit just fine.
Out of near 13,000 installs we've never had a complaint about this nut. We've used this same nut from IMSR Prototype 001 that I installed years ago and we haven't ever considered using anything else.

Yesterday I installed the IMS bearing, RMS, replaced the o-rings on the tensioners, re-installed the AC and throttle body, damaged the PS pulley and had to order a new one, and found a strange looking sensor lying loose and tucked behind some wiring - no telling how long that's been there. I certainly didn't remove it. It has a plug so there must be a wire somewhere.
Today I'll install the cam plugs, clutch and flywheel, air injection pump and other miscellaneous parts on the south end, then install the transmission and new slave cylinder.
Hopefully I won't have any parts left over.
