I need new lug bolts, help pls!

[Master_Axe]

Hi guys,

so, my '80 SL has the standard Chrome rims (or so I thought), 14". However, the lug bolts are dug in deep down inside, and are practically invisible, leaving the rims each with 5 black holes.

On pictures I see bolts that end with the rim, looking nice. However, my bolts only measure about 2cm from the collar down. So I guess I'd need bolts that have a 3cm neck from the collar to the head?

Any help would be highly appreciated. Thanks,

Franz

P.S.: The dealer couldnt find any of those bolts.
