really sorry more wheel stuff

[chimp]

hi

after my last post i felt better but was still confused so here goes

im fitting 15" penta's btw (7Jx15H2 on the rim)

some people have said that these take tapered bolts and others radiused?

i had a look at mine and i get the impression that mine were radiused that now go to tapered (perhaps bored out) afterwards this then leaves 8-9mm of alloy before the back of the wheel (the 8-9mm starting at the end of the taper.)

i hope this makes sense up to now.

so, if they have been bored will i beable to just buy some tapered nuts and bolt them to the existing (standard) studs?
if so do i then buy standard length (not sure what that is) bolts for the front?

also can you buy nuts/bolts in an un shiney/chrome finish (dull, black etc) because the wheels are gonna be black and i wanna match.

mucho thanks
