Working on A-pillar grab handle finally..
I want to sandwich a plate onto the a-pillar for the upper handle bolt.
Where the lower bolt goes on the driver side a-pillar, there is a slot receptacle for the trim, so you cannot rivnut the pillar directly there.
Thus the need for a mounting plate, which I will rivet to the a pillar.
The driver A-pillar trim is not recessed like the passenger side for the handle, so the driver handle will need to be spaced out further from the pillar to give you the same amount of room under the handle. (And for base of handle to be above trim surface)
Rivnut fail. Instructions say workpiece can be .5mm - 3mm thick.. This part is about 2.5mm thick.
(I thought it was 1mm, but that was looking at some harborfreight level that had 2mm increments!?)
And this short tool doesn't give enough leverage for that size rivnut.
Drilled 3 x 3/8" holes with 3 different drill bits to test. I like the unibit for keeping things round, though I worry it may not stay centered..
All 3 holes are a little loose for these rivnuts so that's not helping.
Manual says 9mm or 3/8", but 3/8" is 9.5mm. 23/64" is closer, but still a tiny bit larger than 9mm..
