Seat mounting crush tubes

[SeriesLandy]

I have my drivers side on 3 x 40mm plate welded to the chassis and riveted to the floor, with the seat runner on top.
The passenger side is 25mm box with the seat straight on top so they are the same height.
They seem to be fine and had no complaints at iva.

I may not bother then.

The bolts will be going through 16swg 25x25mm box section and 2mm aluminium floor. If needs be I can go with David's suggestion and put an extra bracing plate on the top of the box section or something?

Thanks
