If you mean the whole clocks, then there is a difference, in that the dial goes up higher on the 24v. If it's the actual mechanism then I'm not sure?

The rev counter gets its pulse from the distributor so I guess the 16 and 24V rev counters must be different which is worth considering if you are changing the whole cluster, but other than top speed "range" I cant think of a reason why the speedo should be different. I think I remember reading that the pickup is on the gearbox - obviously on the final drive.

not sure,

but i think there may be a slight difference between early and late cars?

not actually noticeable untill you connect them up and i think the oil or alternator readings sometimes do not work properly????

but might just be the ones that ive had???
