Thanks for the offer, i'm based south of oxford. Pretty much sorted now though.
If its not one thing its another.... Few unexpected snags hit along the way...
New bearings went into the gearbox easy enough, sealed it all back up and stuck it together, then realised i'd left out the oiling carrier tray thing. Dissasemble and reassemble again, oh deary me, and there was me thinking i was getting good at this! Old bearings didn't have any play surprisingly, but were noisey when spun, same with the clutch release bearing.
New clutch went on very easily, made my own centering tool out of a socket extension and some electrical tape. Simply wrap the tape around the extension to the required diameter for the pilot bearing, then same again for the clutch plate. Happy with that...
Whilst offering up the gearbox (via engine crane) to the engine, the stiff dowels yet again caused trouble. Should have removed them / cleaned em up / deburred them. Threaded in a couple of bolts finger tight to keep it roughly in place, but the continued jacking up and down (even just a little bit) eventually tore some threads out of the engine block. My own stupid fault. The alloy threads are very soft / weak - don't be fooled by the size of the steel bolt! Cleaned the bolt up, blew out the threaded hole and it went back in and torqued up to 64nm just fine, so i got away with that one.
However, the the gearbox rear mount bracket bolt, the threaded hole goes all the way through the gearbox casing, leaving an exposed part of the thread. Corosion and what not damaged the thread on the bolts way out, and it doesn't want to go back in nicely at all. Not solved that one yet. Its 1 of 3 bolts holding the bracket for the rear mount to the box. I'll probably get away with it but i might pack it out with some washers as it does go in someway smoothly.
Treated myself to an electric impact wrench (DCF880) , 90quid well spent. After struggling to cut off the ARB drop links with an angle grinder, i ended up getting them out with a pair of vice grips and the impact and some persistence. Still hard work but quicker than cutting them off. ARB got a bit scarred from the grinder, so a quick bit of paint to prevent any future mot advisories.
Subframe has been offered up to the car via a jack at the front, and the engine crane lifting it via a strap at the rear. Bolts are in loose and it still needs jiggling. Once my generic ball joint boots turned up, i think i'm pretty much done.
All in all, took longer than expected but i've been taking it easy-ish and with limited space.
Next house needs a double garage / barn , and a lift....
Hope no one minds the musings - passing on my mistakes so others don't make them
