Wheel bolts for BBS RA!?

Hi

I have spacers on my front wheels as to fit the bigger brakes without catching.

But I have just bought some spacers for the rear to bring them out the same.

I ordered what I thought were the right bolts from VWHeritage and they emailed me saying they were the wrong ones, and they will send me the ones I need.

Anyway when they have turned up, they are flat, not tapered or ball shape etc.

I'm guessing I cant get away with these!?

Is there a tapered washer/seat I can buy?

Or if I send the bolts back, any ideas which ones I need???

Lengh I need it 33 to 35ish mm

Thanks

chris

Update:

looks like they have just not sent me the radius washer/seat that they should of come with!! emailed..
