Come on guys, group hug.

And we can all sing Kumbaya -- or however it is spelled. Better we should sing it -- I can't spell it.

Paul....Mine is an early built 1971 (Dec. 70) So I'm "thinking" that it is probaby and most likely, a cross recess screw.

Thank you......Doug

I would agree with you my Sept 70 S/N 1914 built 1971 and a Jan 71 build S/N 67?? car both have that fastener type. Along with a few others I was involved with up to S/N 98?? had the same and now we have Dave S/N 16798 as a starting point to work back from. We now need more original cars to see when the change started to occur.

Terry got it right kumbaya to all.

My 1971 built late January 71 is all apart, so I took a look, it is exactly as the 3 photos with the J-nut

Apology accepted and appreciated. 70 #6243 has cross recess.

The cross recessed screw, is this a fillister head. Would the screw have a washer.

The blue on the 1972 hex-head attracts my attention. IIRC in the early 1970s that blue was an indicator of a metric fastener. It was intended as a head-up to the mechanics to reach for their newly acquired metric tools.

BTW: Very nice pictures Kevin.

Terry, I believe that around 78/79 we started seeing the blue colored bolts and nuts from GM.

So if I am off by half a decade (and maybe I am), why is this one blue? Not defending my date estimate, only asking about the finish that looks out of place to me.

Maybe it is a lubricant or something else??

This fastener drove me crazy! It was one of the reasons I spent untold hours putting together a spread sheet that numerically ordered every piece of hardware for my '73 coupe. I went through EVERY page of my A.I.M., entering EVERY part #, then had computer arrange the #'s. ANYWAY, that screw # was used in two other places on my 73. 1) On the Valves In Receiver bracket. 2) The automatic transmission cable mounting and seal retainer. Sure enough, same finish and size. Awesome! Understandably the cross reference probably isn't foolproof, but at least this time it worked!

We need much more data but with this limited sample it looks like the changeover from cross recess to hex was somewhere in the mid 1971 model year. Now we need to zero in.
Am I correct in thinking that no 70-72 cars used a nylon insert.????

I checked my '71 #4001 with a build date of 12/15/70 and it has the same screw as '71 #8555.

My '71 build date 2/2/71 #8417 is the same as Kevins '71 #8555.
