Re: Midget 1275 type 9
You will need one of these kits for a start:-
https://www.morrisminorspares.com/modif ... r-p1238071
You will need a 1275cc Midget flywheel which has been re-faced and indexed drilled to allow fitment of the 7.5" dia clutch assy as per the photo below:- or you could go the whole hog and fit one of these kits:-
https://frontlinedevelopments.com/part/ ... d-gearbox/
There are fitting instructions in the link above but they are not complete so some knowledge/skill will be required to fit the conversion.
Front line Developments can supply you with all your requirements to carry out a successful conversion.

Speak to Front Line Developments (link above).
or
Peter May Racing. https://www.petermayengineering.com/
There are several versions of the Type 9 gearboxes and there are more than one length of first motion shaft so make sure that you have the right one.

Re: Midget 1275 type 9
Sounds like it’ll be easier to change the crank , got to be rebuilt anyway before it goes in
it’s getting rather expensive

It does not stop at the crankshaft.
The rods have to be changed if you are going to use a Marina/Ital crankshaft in a 1275cc Midget block. Which means that you will unless you have the special tools have to get an engineering shop to change/or fit the pistons to the Marina/Ital rods.
A modified 1098cc flywheel suitable for use with a Marina/Ital crankshaft is available from ESM Morris.

Yes it is expensive once you get away from standard.
You could always use a Ford 2000E 4 speed gearbox which is what my gearbox conversion is based on. You get all the Ford gearbox benefits (synchro on 1st
) except 5th gear. Unless you are going to use your Minor for a lot of Motorway driving there is little point in spending all that money. You can always fit a 3.9 diff to give a bit more top speed cruising and make the most of that 1275cc power.

Re: Midget 1275 type 9
If you are running a std 1275 and don't intend to do massive mileage an std minor gearbox will work fine and relative to fitting something else cost next to nothing, they are easy and cheap to rebuild and parts are readily available.
I find you very soon get used to having to stop to engage 1st (or doubling the clutch) and even on motorways if you are preparred to drive at HGV speeds you don't miss 5th.
