any 32/33 box will do the job, series 3, 33 have better syncros, thats about it..
Simon at Competition Gearboxes is a top guy and will look after you,, he's fix half a dozen for me.
the OS Billet centre plate does seem to be a good investment also, will be putting one in my OS box which I just smashed second in
I have a question also : I'm getting a standard box that I've broken, rebuilt, and I've talking to a gearbox guy who is having good results with 4WD (Landcruisers or something) gearboxes, getting the crucial bits cryogenically frozen to harden the metals... has anyone tried? got any opinions on?
its not expensive so I'm prepared to give it a go..
