Converting the selector of a 369 gearbox

Morning all.

Have a problem and hope that one (or many) might have the answer. Car is an A310 that has a 369-02 gearbox.
The gearbox has a single gear selector shaft, and I would like to convert it to a twin selector shaft type. Thought of using the selector housing and selector mechanism from an R25 (5 speed) would this work? Or are there alternatives that I should consider?

Also does anyone have an R25 (5 speed) box available, not bothered if it is broken, as long as the selector mechanism is still good.

Many thanks

I can definitely help.

I have two 25t boxes, both in full working order, going spare. To go in a 310, the final drive has to be flipped as you know.

I also have a 610 box which I'd be happy to swap the end casing with you for.

I ALSO have a 5 speed 369-01 rebuilt for a DeLorean with a 3.8 final drive and strengthened input shaft coupler. All bead blasted and all new seals. It'd go straight in your car... Asking £400 outright for that, plus your old one.. (the strengthened coupler is some $200 alone.)

What a load of goodies you have.

Want to keep my 369.02 in the car if possible but want to change the selector housing and the 'prime' selector mechanism so that I end up with two gear selector input shafts, rather than the one I have, as this will make it easier for me to then install a mechanical sequential changer.

Will the rear cover of your 25 box fit my 369.02 and if so do you think the gear change will still work

If not, or maybe as well would you be willing to sell your 369.01, without an exchange, as I need to keep my .02, just in case the sequential fails miserably Also on the .01 is this a dual cable selector box?

Thanks

Hi Mark

Firstly, and I'm ashamed to admit it, but I can't remember if the 25 boxes use a single or double shaft linkage. Despite having a very close view of them both while stripping them out, and falling over one or the other on a regular basis.... I need to have a quick look but I believe they're really similar to the 369 - a single long(er) arm.

AFAIK the end casings are interchangable across all the 5 speed UN1/369 boxes. The bellhousing certainly is.

If you'd prefer to buy my 369-01 outright, make me an offer It's sitting there doing nothing and has been for 2 years. It was to be part of a low ratio silly powerful 3 litre turbo DeLorean... but I bought the Venturi instead

I need a few bits as well Martin .

The crownwheel will need to be correctly shimmed, question does the crown wheel foul the bell housing?

Its just I heard all this when I was considering building a 21T powered GTA the bell housing had to be modified, this may be due to the design of the 21 T's Bell housing being a lot different. Is this possible with other bell housings, I suppose if you have the correct one for the car it should be ok?

The V6 bellhousing is symetrical internally so the crownwheel can be put in either way around.
