Triumph TR3 - Scuttle Panel Bolt Holes

With the windscreen off, I can now repair the poor repairs done to the scuttle panel where a PO apparently mounted Brooklands type windscreens. There are four pairs of holes in the panel, and the areas surrounding each have been poorly filled in and painted with badly-matching paint. One pair of holes still has sheared off bolts in place that protrude slightly above the panel surface.

How are these bolt holes treated on original cars? Were "place holder" bolts installed in the holes? Are there captive nuts underneath the scuttle panel to hold the bolts, or loose nuts? Piggot's "Original Triumph" shows a picture of a TR2 with four single bolts in place where I have four pairs of bolt holes on my TR3A for the "competition windscreens."

Lastly, what size and kind of bolts were used for this application?

With no intention to use Brookland screens, one option would be to just fill in all the holes, paint the area and be done with it. My preference is to keep it accurate, if possible.

Thanks for help on this one!

The Brooklands Aero-screens had 2 or 4 small screws to hold each pedestal. If there were two Brocklands Aero-screens, there could have been 8 - or up to 16 small holes in the top of the scuttle. The original early TR3A's strainght from the factory came with 4 chromed hex nuts and chromed chamfered flat washers on the scuttle between the dash and the windscreen to accept the TR optional Aeroscreen that was S-T designed to fit these hex nuts. After a certain Comm. No., S-T stopped putting these on. Your later TR3A had nothing here. If you clean it down to new metal, you can MIG weld the holes closed and then get a body shop to re-finish this area flat and smooth. In fact, a body shop could do both the welding and the finishing. If you want to do it yourself, and if you don't have a MIG welder, you could Bondo the holes closed and finish it yourself.

Remember to be careful that you and/or the body shop do not want welding sparks and liquid steel droplets to fall into the wiring under the dash or burn a hole in your floor carpets. OR WORSE !

Thanks for the deep background on the holes, Don. I'm going to fill them in and call it a day. Bondo ought to be good enough for now. Someday (ha!) I'll have the tub off and can do the job right.

Regards,
