FWIW, these are the parts I bought from Cobra Transmissions for my S13 FS5w71c box.
The European box was different from the US Boxes in terms of synchro types and numbers.
This gave me nearly everything I needed. I think I had to buy one unique Nissan radial bearing from Mike F and one other standard bearing from simplybearings or similar.

A bit more of the gears stripped down, just got the last bearing in the sandwich plate to press out.

I think 34 is the one I bought from Mike. So I would assume it is possible to get it from Nissan.

I have ordered it from simply bearings. If anyone has one out to measure it would be a help as I am guessing to a certain extent as it was not in the box in a measurable/identifyable state when I dismantled it

Decided to take the subaru diff out aswell to double check the backlash and then hopefully adjust it.

Can anyone give me a contact to supply a new, balanced propshaft when fitting a 200SX gearbox for a 240Z please ?

Nice work sir.


How do you adjust the backlash then?
They have shims in the the side flange assembly, I took one out on the left and put it on the right side to move the crown wheel but it was too much, so I put it back but will try again later and just take one shim out of the left side and see how it goes as i need to get some o rings aswell before puting it all back.

Sean - Bailey propshafts have made a new one for Dean recently. I think it was £250 + vat for an all new item (not shortened).

I have done a bit more on the gearbox now I have all of the smaller bearings as I thought I would change them all. The main shaft fully stripped as you have to as part of the rebuild. New bearings in the sandwich plate and started building the rest of the gearbox. IMG_20200216_190346.jpg
