What is it?

Hello everyone
I am still looking to learn more about my S4 FEDERAL. Who can tell me what was fixed behind and a little below, each of the seats by means of 4 fixings to the floor. I attach the photos of the traces in the carpet. This has a rectangular shape of 13cm x 18cm.

A roll bar?

Seat runners. Should be black and have a lip to prevent the seat from tipping up. A tab on the rear seat support slots in to do this.

I know they were standard on the Sprint but am not sure at what point they were introduced to the Federal versions of the Series 4. Just checked and the non-tip runners were introduced at Unit No. 9267, which was invoiced in July 1969.

The attached photos shows some. The alu one is a later type provided by Lotus parts suppliers.

The pattern appears to be from the pads fitted to the bottom of the main hoop of a roll bar.

I also thought of a ROLL-BAR. But fixed only on the Polyester of the bodywork... Not very serious or solid. I put the garlic back on the seats. I chalked the fixing points and the outline of the trace in the carpet. It should be seen that this attachment is at least half under the seat. Another question mark

To me, it looks like a speaker or Radio component fixing.

The same hole are before each seat near the door.

Is there perhaps any evidence that a matching rectangular plate was also mounted underneath the floor?

If so, bolting through top and bottom plates might have been a way of transferring roll bar loads through the floor without cutting large holes, or having to finish welding up the frame in situ etc.

Cheers

OK perhaps
