harness mounts

[mark]

Now ive got my roll bar (thanks ash) i want to position the harness mounts.

I have welded in the cross brace but the measurements in the book between the threaded bosses says "to suit seats"

I plan on using fabbys wide seats...........im not fat im just tall and generally big!

So my question is if i make them to the book spec will this ok for these seats and iva?

Thanks
