66 Front lower shock bolts

[Brian K.]

Did the original front lower shock absorber mounting bolts have a serrated washer on the 66 model year? If anyone has a picture of an original it would be much appreciated. Sincerely Brian

Re: 66 Front lower shock bolts

Brian, does the 66 JM have any details? I know that my 63 has serrated washers on the lower mounts, I think that 63/64 maybe the only years, I believe that the most have the lower shock bolts with the fixed washers, just about the same as the hood hinge bolts, maybe a tad longer though. I read my 63/64 JM and its funny that it does not even mention serrated washers. Although I believe that's a era.

Re: 66 Front lower shock bolts

My 66 JM states "The lower attachment bolts are black phosphate recessed hex-head bolts with loose washers" no reference to serrated washers. Hope this will help you!

Re: 66 Front lower shock bolts

Thanks guys. I had checked the JM and read the description, but still not sure plus we all no the JM is not perfect on everything. I would like to see an known original example for headmarkings and what the washer looks like.Sincerely Brian

Brian, 63-mid 64 used the serrated washer bolts after that all were non serrated. Rich.

Also know headmarkings I have seen on 66's are C, Anchor, RBW, E and at least 3 more. Rich.

Those are commonly referred to as "captured free-spinning conical washers".

The design department (years ago) I was at used the trade term "SEMS". I think that was just one of the vendor trade names as I recall.

The shank just under the hex head, where the washer is, is just under the minor diameter of the thread making these screws a less torque yield when tightening. So use care not to over stress and snap the heads off.

Re: 66 Front lower shock bolts

Brian, I have a mostly untouched 1966, owned since 1967. The shock, lower bolts have a recessed head, with a plain flat washer that stays with the bolt, someone mentioned captured washer. The end of the bolt comes to a point, and the head is marked with a C, with 3 lines going through the letter.

Ed,

I have the serrated bolts for my front shock bolts. Are the ends flat to do they come to a point as I have two choices of bolts.

Thanks

Thanks

Jerry serrated washers with pointed ends are correct for 63 shock lower mountings, if you still have them that’s great, 63 has serrated washers in a few locations. If you need more info on locations let me know.

Re: 66 Front lower shock bolts

Thanks Ed. But are the ends pointed or flat?
