Thanks for the quick response.
In regard to the mechanism location, thats just what I was told by a mate, so not necessarily a reliable source, however he hasnt been wrong before, so this would be a first.
I didnt think to check compliance places. There are a few memebrs on here from compliance workshops from memory, carizma or something? I just need to find one that would do an R33. Ill dig around in a few threads. Thanks.
