1964 1/2 - 1965 / Holes in dash

« Last post by birddog on April 29, 2024, 03:36:18 PM »

I'm trying to do the final welding on the dash. Curious if anyone has pictures of an original dash, especially underneath. The first picture is the possible location of GT fog lights switch. Does that location and size of the hole look correct? I would also like to weld all other holes under the dash. Some are pretty obvious that they were added at a later point. Others I can't tell for sure. Thanks. BTW the car is upside down on a rotisserie.

1969 - 70 Shelby / Roll Bar questions - Fastback

« Last post by AJ on April 29, 2024, 03:33:18 PM »

For the fastback roll bar,  were spacers of any kind used at the upper or lower mounting locations

Next question.  Should the plastic roll bar trim be black or dark graphite.

Thanks

I use these:


AMK Products P/N B-11557

Those will no doubt work but are not the posi drive given they do not have the markings. It all depends on if you are concerned about doing it the assemblyline way or not.

From the factory the outside mirror used the posi drive type machine thread screw. They have a counter sunk head like the generic mirror screws . Posi drive looks like a Philips cross head impression however they have a slighter different shape inside the allows for more torque to be applied without slipping. They are identified by 3 slash marks in between the Phillips impression . I believe that they are mentioned in the MCA rules. The picture I posted is to show the marks on the head. Disregard the flat head and sheet metal threads. NPD used to sell them but can't say currently.

That's interesting. They seem to be hard to come by.  When I search for 376770-s100 screw that is listed in the fastener spreadsheet and on the assembly manual page N8-8505 I come up empty.

My original inserts on the driver side both spin.  I purchased a nutsert tool from Amazon, the one with the long arms for leverage,  and was able to tighten up both of the inserts. I used a 10-24 tap to clean out the hole and reinstalled the mirror using 10-24 Phillips Oval head screws,  not the Phillips Oval head sheet metal screws that were installed originally.

If your originals do not spin I recommend running a #8-24 tap through them to remove any paint that might be there before trying to install the mirror.

Most are steel. Late cars sometimes brass
