Can anyone tell me what these holes are for? There are 2 more on the opposite side.

Thank!

Geoff, I'll take a shot at it.
Someone has removed the bolts that hold the bracket for the radius arms. Even though the GT6 was last produced in 1973, Triumph didn't change the body molds for that panel. Still there on the 1980's ones.
GT6 roto flex.used one side and the Spitfire the other on each side..
Fix it by putting a couple of bolts in there, fine thread 7/16, I think.

Do you have radius rods? They're a big part of the rear suspension.

Thanks, that makes sense. Will use rubber plugs.

No. I think what happened is that the previous owner who started the restoration left the holes exposed when he installed the insulation. Probably forgot that they were not going to be used. Car has the standard 1975 set up.

You might want to look at this page, https://rimmerbros.com/Item--i-GRID005748 In particular item # 155930R and their associated hardware.

They are important bits of the suspension.

The radius arms are there but are bolted to the left & right of the holes in question. I can't see anything under the car that would use those holes.

I just found this picture the previous owner sent me when the car was being stripped. To the left you can see where the radius arm is bolted and the holes in question have bolts in them.

This shows it from the rear, suspension side, the holes just below the e-brake cable. This is a 69 body but they all have them in the same place. At least all of mine do.
other side I the same. On my other 69 these had rubber plugs in them. This car did not so they were probably pulled by a PO at some point.

I agree- be reassured, they are certainly nothing to do with any part of the suspension.
Originally, they will have simply had rubber bungs in them.

As to their function? - I do not know.

This is just a guess, but I think It is possible that once the car had left the production line, they had no function ar all.

Various holes in such places as the boot/trunk floor and the holes in the inner sills/ rocker panels were more to do with giving access during assembly-for the arms of spot-welding machine for example.Those on the exterior were then sealed off with rubber bungs.

These particular holes are too small for that, but perhaps they were to secure that body part during assembly possibly in a jig.

Someone, somewhere will know...

Geoff,
Wayne has the right idea. That panel was designed to accommodate both the Spitfire suspension and the Rotoflex GT6 set-up. The trailing arm bracket for Rotoflex has to be mounted closer to the center of the car to make the geometry work. When the panel is used on a Spitfire, the Rotoflex holes are plugged. When used on a Rotoflex GT6, the Spitfire holes would have been plugged instead.
Cars built before the Rotoflex GT6 was introduced don't have those extra holes.
All the best,
Paul

I am sure you’re right! - your explanation makes perfect sense to me now.

Spit radius arms used the holes closer to the outside of the body - Gt6's with roto-flex used the inner set - on a Spit you can used the inner ones but WILL NEED to get longer radius arms (have them made with heim joints also) and the toe change over travel will be reduced (out of Spit Comp Prep Book - will also need the additional bracket inside tub to reinforce the area ( works well and my Spit and Herald will both get this mod)
