Hi,
Can anybody confirm or deny a rumour that I have head, that the 4 speeds fitted to the last of the Beetles (1976) had an overdrive fourth gear.

Thanks Jade

I think what you're asking is do they have a taller 4th gear?

no they don't it is actually shorter.
73-76 IRS bug boxes were all geared the same, they have the 0.93 4th gear unlike the pre 72 which have a 0.89

they made it shorter to keep the revs the same at 100km/h when the taller 3.88 diff was fitted to maintain proper cooling fan speed.
