Does anyone know the bolt size that goes in a Mitsubishi gt600 drive shaft? I need it to bolt on my clutch but have looked at most metric bolts and an M8 seems to fit but it only goes in 5 mm before becoming too tight.
I would try and look at the pitch of the thread. Metric is measured in millimetres from the high point of the thread to the high point of the thread next to it. It could typically be 1mm, 1.25mm or 1.5mm.
Of course you are right AVB, I got carried away with the Mitsubishi bit, I guess there is a good chance the clutch was made in the States so the thread could very well be UNF or UNC
I'm like you Norm I assumed Mitsubishi is Japanese so it's metric but it could well be imperial. Sorejo is the motor out so can you take it to the industrials supplier and try a few bolts?
