[SCOTI]

I considered investing in one of the Rivnut tools but the couple I've used @ work left a little to be desired. The higher end tools look enticing, but I doubt worth the coin vs how often it would be used for my situation.

I was using all-thread, GRADE-8 nuts/washers, & wrenches for the ones I've installed on my dually but found the small 'installer' set-ups in one of the hardware assortment sections for each size I use. These have shorter lengths like a carb or exhaust manifold stud. They've worked well & were <$10ea. I did my trans tunnel/hump & driveshaft tunnel covers w/them on my '64.

Nice work on the updates. Your thoroughness is noted
