Have a 60 model with a gearbox that i,m replacing. Not sure if it is the original or not. Can anyone tell by the numbers. What should i put back in to run a 1776. Maybe something taller.

Gearbox number 5324354 Thanks Aaron

Jaksc, is it a split case trans, ie has a join/seam down the middle of the case?

Not a split case. Thinking of. Buying ah rancho. How do I know what I need or are they all interchangeable. Aaron

Yes the swing axle gearboxes after 1960 are all interchangable, with only ratio changes made as the stock engine power went up, with a 1776 I would think a later standard rebuilt box would be suitable unless you plan on dropping the clutch, or racing.

Thanks mate! Could you suggest a ratio that will suit. No racing just regular driving but would like it to pull up hills. Aaron

The stock ratio's of the 65-67 swingaxle are great for around town, my 66 has its stock 1300 box in it with a 1600 pushing it along easily with city traffic, if you do more freeway/country driving I would aim for the 1600 ratios

Would you know the difference in the ratios. Aaron

Can anyone suggest a ratio I should be looking for? Buying a new box but there seems to be lot of variations. Aaron

Stepping from your 4.375 diff up to a 4.125 is a good upgrade if you have the power.
This is what 1500 beetles had.

The 1500 and later beetles used a longer axle and tube, and after mid 1972 the nose cone mount is different,
but with a bit of work these can be fitted too.

Will a 1500 box bolt straight in and retain the original axles. Aaron
