That is how I've done it.

There was a general consensus that putting the threaded bosses through the cross bar was a very good solution, and there is no need to use the 3mm steel bracket to fit them on the cross bas as explained in the book. I think a lot of builders did the same as me.

After, concerning my car, I kept the exact transversal position of the threaded bosses as explained page 53 of the book (254mm=300mm=254mm). They don't fall directly behind the harness holes of my seat, as I did my roll bar before buying the seats, and I guess every seat model has its own spacing of harness holes. But it is latterly acceptable, as, IIRC, there is a lateral angle tolerance in the regulation (needs to be checked on your IVA manual)

Then I bought Sabel harnesses. Harnesses need to be the short strap style or single seater type, as the saloon car type have way too long shoulder straps.

Hope that will help
