Not sure, but doesn't the cross bar have to be the same diametter as the roll over bar, did on SVA because that was one of my fail points. Ray
To make a car go faster, just add lightness. Colin Chapman - OR - fit a bigger engine. Chippy

says in the manual, threaded bushes have to be welded at both sides of the tube, so they have to pass the whole way through the tube they're in.
interestingly though, it doesn't say what happens if you just weld the eye bolts to the tube, with no threaded bit, which is how my chassis was
done before i got it (wasn't built as a kit car though)
All Vehicles
What to look for:

Evidence that anchorages in a vehicle of the same, or a very similar type have been subjected to a seatbelt anchorage strength test to “European
Standards” by a recognised authority. This may be acceptable where there is clear evidence that the structure is identical to the vehicle originally
tested.

Welding should appear neat and of good quality; whilst it is impossible to judge the quality of a weld just by looking at it, messy welding is rarely
strong welding.

Bolts used in structural areas should be of grade 8.8 or better. Such bolts will be marked 8.8 or 12.9 on the hexagonal head, however, cap-head bolts
or 7/16" ( 11mm ) UNF seat belt anchorage bolts (with an anodised finish) not marked in this way may normally be considered to be of equivalent
strength. Bolts should be M8 or larger.

Threaded bushes should be welded (at both ends) through the tube, and not end mounted on the surface. (A threaded bush may be attached by its side
surface to a structural component).
