Can I fit a 71 super gearbox and axles to a 66 bug?
hi all,
The title says it all - can it be done and how hard is it?
Ive heard that the supers had better gear boxes and the improvements over the swing arm suspension helped considerably.
I've got a box and the axles and will eventually have the 1600 to go with it all - so what else needs to be done? I've never pulled a gear box from
a super or 6volt so I'm not sure what the differences between the models are as far as mounting.
Cheers

at a guess, nose cone mount would be different, just use a mid mount anyway, would be a good upgrade, and... obviously IRS pivot boxes, and some minor
love taps to the frame horns to clear cv's from memory, and different spring plates to suit the IRS setup, im pretty sure thats all but havent done
the job myself

It's a huge job you're looking at
To convert the 66 to IRS is a body off job which ends up exposing other work that needs doing like heaterchannel/floorpan rust etc
and you will still have a link pin front end.
You would be better off getting a 1500 swing axle box.
Exactly the same ratios as the Sbug box but will bolt straight in.

Thanks for the advice Joel.
I think my car is fairly rust free, but pandora's box looked pretty innocent until it was opened.
I wanted it for the better suspension feel - but do the ratios help for freeway driving?

If you're running the stock 6 volt 1300 box now switching to either a 1500 swing axle or sbug box (both have same ratios) wont do anything for the
acceleration but cruising speed will be heaps better.
To convert to IRS you would need everything from a superbug or type 3 - gearbox, axles and CVs, trailing arms, spring plates and torsion bars, the
take the body off and get the pivot boxes for the trailing arms welded in using a jig, proper alignment is critical.
My 70 1500 bug had an IRS conversion, it's just having to take the body off that makes it a PITA job.
