The hose fittings that JE supplied were crap, they leaked sieve! I used my own fittings and it's be OK for 3 years. The position of the slave is very important, when everything is new it needs to be very near the END of its travel when the clutch pedal is pressed, as the friction plate wears the slave piston at-rest location moves further and further up is cylinder. I did get this wrong at first and when I pressed the clutch the piston popped out of its bore!
I ended up spending a load of money getting the bellhousing machined as the spigot bearing did not engage correctly nor did the clutch friction plate splines. From memory I had over 10mm machined from the back of the bellhousing, the back of the bellhousing is 'blind' so the recesses in it needed machining out.
Now if I had one of the thicker RV8 flywheels fitted the clutch spline engagement may have been OK without the machining but the spigot bearing engagement would still have been poor or not at all!
I did consider telling JE all of this but I had already waited 10 months for a set of close ratio gears for a R380 gearbox which then did not fit my gearbox so I had had enough of him. Also he knows everything so he did not need to hear a customer telling him that his bellhousing needed a load of work doing before it can be used!
Maybe people are using it without any machining but the input shaft of their gearbox will be waving about in the breeze due to a lack of support and the splines on the input shaft will only be engaged by about 10mm. (This is about half the available width of the splines on a standard Borg and Beck style of friction plate. My plate has an offset boss which is 30mm thick, I have 29mm of engagement which is nice!)
AJMHO!
Wow, you had it worse than me!!
I was quite unimpressed with mine but at least it lined up properly.

Muscle Manta and I were going down the route of sticking a Cossi T5 with Quaife gears in his SD1 at some point in time. He got hold of a TVR bellhousing but really it was too deep because the Cossi input shaft is shorted than the TVR one, we had the back of it machined and with careful selection of a decent friction plate it would have been OK. The spigot bearing carrier would have had to be machined up and it may have had to move the bearing slightly out of the crank towards the gearbox. We had the front bearing retainer of the T5 machined down in a lathe because it is larger than the hole in the back of the bellhousing.
Er thinking about it he is now not going to use the bellhousing, I can see a deal appearing on the horizon!

I too went from LT77 to T5 but in my Rush.
I looked at R380 at first but couldn't find any (2wd with car ratios) for sensible money.
In the end for me it boiled down to which (good quality box) box I could buy.
The Cosy T5 has the gear lever in the correct place but then you need to sort out the bellhousing/clutch, where as the TVR has the correct bellhousing/clutch but you need to make a remote to bring the gear lever back.
When I was looking the few Cosy T5 boxes I found were knackered/high miles, where as most of the TVR boxes I saw seems nearly new/low miles forms crashed TVR's. Also think they are stronger as has been said.
They are a fair bit lighter than the LT77/R380; but are wider, I had to cut a hole in the drivers footwell panel of my Rush to fit although didn't have to touch any chassis rails - but it is close.
Some pics of my remote extension setup:

That's an interesting setup that you have there! I may have got this wrong but looking at your pictures it strikes me that your gear lever will always remain vertical when you push the lever forwards or backwards, is this the case? If so I guess there is nothing wrong with that at all!
Edit...Ignore what I've just posted! I can see that the pivot point is in the 'normal' place, i.e at the bottom of the gear lever!

...and my version for my WC T5 in my Rush
Works much better than I thought. bearings are PV80 (self-lubricating plastic) stuff and uses a simple UJ.

Yep I have already watched that video.....any now worried what I will get.....
If I could find a proper rebuilt one I would be happier....
But you only have people say so on ebay, no guarantees that things have be rebuilt.....
But the T5 is now rarer then the R380.......and I took me 18 months to find an R380, only to find out it doesn't fit, without chopping bits out the chassis.
Ebay is good, and ebay is bad......you just gotta be careful buying everything from there.....
If anyone knows a good T5 rebuilders.
cheers

I see a seller on egay selling a TVR T5 gearbox and bellhousing, separately mind you.
Claims low mileage etc...but holy moly, what a price.
I'd be tempted just to buy a brand new unit at the money he and others are asking and know the unit is perfect

Or the Toyota units ? Cheaper being a W56 ?

Another option might be...if it fits, is the Nissan 350z CD009 trans.
Seemingly they're incredibly strong, but obviously you'd need to sort the installation.

There are places in the US that make adaptors for various engines, although dont see anything for the Rover/Buick
