Its round about $45.
You can see the other Titanium stuff they do (diff outdrives, cvds, hinge pins etc etc) at their web site
http://www.titaniumracing.com/site.html
i dont know whether they will ship to the US but e-mail them you never know. I have been in contact with Paul white their sales manager. If they cant ship direct try Apex models
http://www.apexmodels.co.uk or snetterton model shop
http://www.sm-modelshop.co.uk cos they are both supposed to stock Titanium Racing products and are first class mail order specialists
Good luck
Rich
