GP150 Indian Vijai super gearbox use for a tourer

I have a new 200cc GP Uni casing which I'm going to build up with a decent performance cyl kit.. with the plan of being a reliable tourer
I do have a GP150 Indian Vijai super gearbox 1991 which I 'm just stripping out of a cracked casing.
Are these gearboxes any good? From what I have read they seem OK but would like to know if anyone out there has used one for a build.
I will likely go with the GT 240 kit, clutch undecided yet.
From an initial inspection the gearbox is in decent order so seems a good idea to use?
