I just received a GTA steering wheel from AFRA. Price was the best I've found, but still expensive. I notice it's a little diferent than the one shown above by classicalfas. You can see the holes in the spokes are a bit smaller. And the screws on the hub may be recessed more on mine, but that is hard to make out. The construction seems to be great and the aluminum is nicely polished. Actually, it may be a bit too bright, plain aluminum might have been 'sportier'. The only 'flaws' are on the horn button, the alfa logo is a bit crude and roughly done. But frankly, that may match much of the other fittings in the GTV ;-).
Euro 382,50 plus 57,01 express shiping from Italy to California (took 4 days).
It was expensive, but that's the cheapest I've seen for these, and AFRA was great to work with via fax.
