Onyx.... What badge type did you have??? Do you have a R33 ??? I know that the series1 R33's have two different rear boot badges/locks, there is a silver and black badge found on the 92/93's and then it changes to the Pewter ( Dull metal ) look on the later 94/95 models.
When my R33 was badged at the back I looked around and found just about the only pewter styled badge in Perth at a wrecker.
Basically if yours is an R33, if you have a silver and black style badge you should find one at a local wrecker dead easy, if its the pewter type then you will have a hard time finding one but its still worth looking around. If you aint got a R33 try the local Jap wreckers anyways becauseyou never know
I bought mine for about $80 from memory then with a bit of fiddling took the badge portion from the lock and transferred it to my old lock ( If you have a look at the back you can understand the badge is just clipped in to the lock which can be removed )
If you have troubles finding one send me a PM to remind me and I will dig up the details of where I sourced mine from
Well that was supposed to be a quick response but I appear to have dribbled on so I will leave it as that.... let us know how you go
