My 04 roadster has a 22mm dia. tow hook. Try finding a bolt that size.

 

that one looks very similar to the stillen design... i know they are having alot of problems with it because every tow hook seems to be different reguardless of production date!

so the bolt does not always work...

My vote is still for the Zee-Bracket which we do sell

Plus the Zee-Braket fits on the NISMO Replica Front Bumpers!
