Did you need those 'spider'-like wheel bearing covers which have the tapped hole for screw attachment too? Otherwise the kit per wheel contains the disc, the rubber edging piece, the screw and a large rubber washer.
I have just one new kit and can gather enough second-hand parts to do the entire car: not sure of 'spiders' yet though. I would have to confirm with my post office the cost to Riga (if that's where you want them), so if interested you can mail me at
paultill38@gmail.com for further discussion. Conversely you could possibly get new from the likes of Skandix, which are probably nearer you.
