Lotus7racer Posted June 5, 2003 Share Posted June 5, 2003 I have a 1992 Westfield fitted with Sierra differential. I believed this is 7" and has 3.6 final ratio (not too sure). I would like to replace the gear to 3.2 or 3.3 for Hayabusa Turbo application. Can someone tell me where to buy the pinion & gear for 3.2 or 3.3 for Sierra diff? If I couldn't find one, can I use a 3.6 in this project? Thanks Quote Link to comment Share on other sites More sharing options...
Mark Stanton Posted June 5, 2003 Share Posted June 5, 2003 Try Phil Stewart at Road & Race 01959 525105 or SPC (Steve Perks) in Redditch - sorry can't find his No. Both are specialist transmission people and supply many WSCC members Quote Link to comment Share on other sites More sharing options...
