Hey guys

need a cert for a 5 speed in a coupe with roadstar diff, 13" wheels and sunny 60a 5 speed. Apparently the amount the speedo is out is too much. Any idea's what sort of speedo drive might help correct it within acceptable limits?? c20 vannette maybe?? and where you would get said drives from. Ta

how soon do you need a speedo drive?
i have spares from vanette boxs, and 56a boxes too.

no huge rush mate, just need it for cert. Need a 19t, which i'm hoping the vannette has standard?? (never had anything to do with them so have no idea!!)
