LR seat belt bolt threads
Can anyone here confirm the threads for current LR OEM seatbelts?
I am installing rear jump seats and belts on my '85 90 and have a question on the mounting bolt threads.
I am using LR lap belts which include captive bolts. The bolts have metric head marks, "8.8", without any SAE type slashes. I always understood that 7/16 UNF is standard for seat belt bolts, and a 7/16 nut easily threads onto them, only slightly binding when it reaches the blue Loctite LR nicely put on the bolts. My thread gauge seems to indicate 7/16 UNF and the threads match a 7/16 bolt, but the bolt head markings are concerning and seatbelts aren't something I want to guess with.
