An apparently early sprite gearbox has popped up locally for sale, and I was wondering after having googled the topic unsuccessfully how many variants of ribbed gearboxes there were...
see: https://www.trademe.co.nz/Browse/Listin ... 1543822896
especially in view that I have a Marina 1275 engine, and a 1098 Morris ribbed gearbox (in appropriately, a thousand pieces) planned for my A30
any thoughts? worth persuing? I was working on the theory that the A30 tunnel & floor needed work anyway, so may as well fit a different box while I was at it...

Re: Ribbed sprite gearbox
Overall gearing (includes diff)
1098cc and 1275cc Spridget: 1st 13.504, 2nd 8.085, 3rd 5.726, Top 4.22, Reverse 17.32
1098cc A35 and A40: 1st 15.27, 2nd 9.169, 3rd 5.95, Top 4.22, Reverse 19.665
I think it means you will need to use the gears more if an A35 or A40 box as it will run out of revs quicker until top gear.

Re: Ribbed sprite gearbox
Duncan, the early AH Sprite gearboxes were smooth case, so this is not original equipment for a 948cc frogeye/bugeye nor a MkII. If it's a genuine Austin Sprite gearbox (rather than an Austin Healey Sprite) then it's from a 1971 1275cc car.

Re: Ribbed sprite gearbox
Could even have come out of an A40 MkII, A35 van, or even dare I mention it a MM ..

Re: Ribbed sprite gearbox
Duncan, I know you guys are handy down in NZ so might not be concerned about this but the off the shelf conversion for a marina here involves modifying a 1098 flywheel and using a 1098 clutch.
So the 1098 ribbed box with mechanical clutch rod might be more of a straight fit than the 1275 .

Re: Ribbed sprite gearbox
thanks guys for all the info, I'll check with the accountant (swmbo) and see if funds are released.
Don't fancy my chances as I was advised yesterday that my employer is making me redundant next month. but you never know.
I too had the thought that original Sprite box would have been a smooth case so a ribbed one would have been either a later one, or from something else.
If I do end up getting it, at least it would be useful for identifying what goes where when I eventually get cracking on the A30 build, which in itself may be further away now I'm job-hunting...
