Hello everyone. First post on here!

I recently decided to revisit Memory Lane & bought a MK2 8v GTI. Takes me right back!
3 door Royal Blue metallic & very straight & tidy. Bought off another forum member, Dave.
As with all cars there is some minor tidying & detailing to do which brings me to my question. The wears 15'' BBS RA's but the black nut covers are missing. I've managed to get the standard black ones from VW (29P each!) but the cover for the locking wheel bolt is obsolete. Does anyone on here know what can be used as a substitute?
Cheers,
Steve
