I have the AC delco torque adapters, both in 3/8 and 1/2in.
I love em.
A little bulky for some things, but handy to have around.
And years ago i picked up a little craftsman torque wrench, i got inch lbs and ft lbs mixed up.
Buying the inch lb/NM version by accident.
Best mistake i have ever made, i do google conversions if i need ft lbs.
IIRC it's max is just under 18ft lbs.
Perfect for transmission tasks, and most of the DOD delete task i did over the past few weekends.
And i used the grommets in a felpro upper kit i bought, it has only been a few days but so far so good...
I did grease them up pretty good in order to get them to seat into the valve cover.
Time will tell how good i did.
