seat belt anchor points
As many of you have already pointed out I've done a poor job of my top seat belt mount welds. Please have a look at the word attachment where
I've shown what i propose to do. I'd like peoples honest opinions.
by the way, i don't want to grind off what I've already done.

I would recommend you read section 5 seat belt anchorage strength assessment of SVA manual.

I'd do what the others have suggested
PLUS
Add a bar (removable if needed) from the middle of each set of seat belt mounts to the rear engine side tubes - that way the force of you're
body on the seat belts has to break / bend / twist the existing tube and also pull in the chassis side rails at the side. If you can do both
you're either the fattest man alive or probably cheese wired by your seat belt harness.
I have known someone fail SVA for just welding to the top chassis rail as he raised up the mounting by a couple of inches and therefore induced a
twisting motion in the rail.

Yup. But I don't see what the horizontal plate welded under the triangulations is supposed to do??

Fair enough- though it will reduce mean that each triangulation fillet is welded on one side only....

I see no issues with that, fully seem weld it.
Remember to radius the edges everywhere in the cabin including around the harness connections behind the seats. Where this is not practical like on
sheet metal sections use plastic U section. How’s the dash? is it rounded at the bottom?
Would like to see more pictures of the car.

Does your steering column have a collapsible section? As it looks very straight

i've altered the steering column since i saw the bit in the SVA about not having a straight connection, can't remember off the top of my
head the angle i have to achieve but it'll mean lenthening the main shaft and shortening the lower shaft.
both have splined ends, i was going to cut, sleeve and weld them.
or i'll be looking at alternatives at Stoneleigh on Sunday!
Not sure about the dash, i need to get my head around the mini windscreen/spaceframe junction.
i'm tempted to mold the whole thing in foam and make a one off fibreglass dash but not sure yet!?
i've changed the pedal box since too!
