George - big time welcome! I think your the guy we've been waiting for!
Finally someone who also has the "LF" fastener. You mention only one found but even at that its great news. Like I've mentioned before, I have more of those than I care to count...
I was hoping you or someone could help me out with this; the pic below shows a fastener with the end pinched off. I have others that have threads all the way to the tip. I think I read somewhere that the pinched off version is an earlier production fastener. First is this correct, and second when did the transition take place for the all thread?
In addition, I've been trying to find out what the term is for this cool hex flange pattern. For a lack of better terms, I'm calling it "shamrock/clover" hex flange. I have quite a few of these as well. If you know the term please let me know.
Our cars were built around the same time (mine 12A LOS). Is yours a NOR or a LOS?
And finally...your glass beading results are great. Are there any home style/weekender blasting machines you would be willing to recommend?
Bottom pic shows the fasteners for the RS Actuator Support. Again, not sure what the correct term is for the washer on the nut-end...I'll be throwing these in as I get them completed. If their wrong holler...anyone.
