well she did me proud today, my bosses transit dropped its propshaft o nthe way to work and the scimitar towed it for 10 miles fully laden with building materials, but..... later on today she lost all her gears it stayed in reverse regardless of what was selected, then it got first and second and nothing more. the synchro on second has been kaput for a while now, jumps out on the overrun. so ive been toying with the idea of a new box for a while.
apart from the standard 4 speed is there anything else which will drop straight into an se5a manual with overdrive? just thinknig if i have to change it, is there a better option?

Nothing that will drop straight in.

Type 9 five speed needs a cable clutch conversion, T5s are expensive and difficult to do, too.

Best bet is get another Scimitar-spec 'box and rebuild it yourself, especially if your overdrive is working well: they can be found for peanuts in the classifieds in Slice. Or rebuild the one you've got if you can keep the car off the road for that long.

If it's the early type, LH overdrive, then you can get all the seals, gaskets, bearings and synchro components from Burtons or BGH Geartech and Haynes's Capri 3.0/2.8 book will tell you how to do it.

The later (1974 - on) J type overdrive 'box is harder to get bits for but still doable.

There's a knack to getting the torque loading out of the overdrive so it comes off the gearbox easily - I can't remember it, but someone on a Triumph or MG forum probably will. Once it's off, leave it alone and don't be tempted to dismantle it.
