taking them off my 67 for first time and its fighting me with every breath.
of course the first one I try works OK until the last screw that strips out and
cant access the backside to help it out.
Solution was to cut a slot in the screw,without hitting 1/4 or wheel well trim.
I used my multitool with a Milwaukee cutter .
I could then use the slot to chisel it counterclockwise.
This was the first wheel(right rear) and on doing the rest,I noticed the screws had a different head on the RR than the other 3.I doubt it was ever changed,so chalk it up to production variations.

The one on the left (pic#3) is the type I am familiar with.

My guys used to call them "B96* Nails".

If they hit torque without fully seating they would take a hammer and smash 'em down to make the repair.

* B96 is the RPO for the wheel opening moldings.

yea Ive never seen the washerless ones used either but they are the same size,self drilling,so
fit and function is 100%.
Im very tempted to find some screws just like the oddballs and put it back the way it came apart.

production variances,reminds me of the one I took apart almost 50 yrs ago that had an oval bushed A frame
on one side and a round one on the other side
