Can anyone suggest how to undo the two upper nuts on the rear of the two upper bolts holding the Diff Plates to the Diff?

One of them is almost visible in this pic.

I believe they're lock nuts.
(And made of pretty soft metal)
I use a stubby ring spanner and crack the threadlock by giving the caphead bolt a 1/8 turn to free the locknut.
The actual cap head holds are fixed to nuts welded to the diff plate.
If that makes sense.

That was exactly my fear.

Managed to remove the passenger side front diff plate by gradually turning the upper bolt clockwise then anticlockwise repeatedly over about two hours.

As luck would have it the rubber bush in the passenger side plate seems to be in perfect condition.

Unfortunately this has not worked with the drivers side bolt, it simply refuses to move at all, but it is obvious that the bush in this plate has completely failed, allowing the diff to move about easily.

I am trying to think through methods of removing the bolt destructively, perhaps by cutting through the plate itself, but nothing is really proving obvious.

Any suggestions welcome.

IMHO,my thoughts exactly, and the beauty with a competent TVR mechanic, they spot other problematic areas which us meer mortals do not spot, so budget in for spending a little more, "You cannot put a price on your safety or your families.

I have to admit, I am a little surprised by the replies: "Just throw money at it"

I think I may have completely misunderstood the politics of PHers.

It's just the situation l am in and yours is probably different?

If you don't have to work weekends and have time on your hands thats great. I would rather work a full day Saturday and half day Sunday , than being stuck under my car and not getting anywhere with the car, and loosing out on a day and a half's pay at time and a half, and double time on a Sunday morning. biggrin

2 - 3 hours labour l reckon for a decent TVR Garage, and of course the VAT on top.

Just found myself watching Fifth Gear recently aired 15/06/17 on Quest, watching an item on a Tamora which mentions failed rear diff bushes - "Budget for £500"

If I had paid someone else for all the work I've done on my car over the last five years (including two twin head gasket replacements, three T5WC repairs, suspension rebuilds, clutch repairs, cooling system overhauls, several valve shim fixes, brake caliper repairs, plus many other less memorable jobs) then I would be bankrupt several times over by now.

Sure, my car has a slightly harder life than most, because it mainly does DN events, but that is why I bought it.

For some the throw it at a specialist with a credit card is their only option due to lack of time/skill/wish to actually do the job themselves.

However, you can also look at it like, a specialist is what £70-100/he, if you can do the work yourself, it is a decent saving! More than most would be paid for the same time frame.

The economic theory of Specialisation suggests that I should concentrate on my day job, because that is where I'm most productive and efficient, and pay someone else to do things that I suck at.

However, I have always thought that was very simplistic, because it doesn't take in to account the fact that I can take much more time over car stuff, and perhaps even do parts of that project more effectively than someone who has a ratecard/quote to adhere to.

More importantly I means I am in control of costs incurred, which is rarely the case when you hand over your car to someone else.

If you really want to see how that works, try comparing buying a house using a solicitor/conveyancer with doing the conveyancing yourself.

I'm quite happy to sort out several things on my car, but as Clint Eastwood said "A man's got to know his limitations", which could be for me, time, seized nuts and bolts, and swearing. Specialist Tools and access might come a close second biggrin

Aide - that's very kind of you!

However, I've given up on this for now as I absolutely have to finish getting the car ready for a trip to Germany next week.

Should have it back on the ground by midnight tonight, unfortunately not many opportunities for a shakedown before leaving on Tuesday next week.

Looking forward to seeing how the freshly rebuilt T5WC performs, I'm expecting it to be a little noisy at first. The change (when static/engine off) is very firm but precise, which must be due to the new springs/pads etc.

Thankfully it's usually the PS fluid that I forget, but this time it was nearly the PS return hose clip that I forgot.

It's still on axle stands, but in my defence I have done a full brake pad change (front and rear) and bled the brakes with the help of my GF who is the best at this. She will always report pedal feel perfectly, whichever car, whether brake or clutch - awesome!

Same from me - especially after your superstar help getting my fuel rail back into the car - so let me know if you do when you're back and I can come over too as you need

Thanks Alex - much appreciated!

Last night I noticed that the diff output flanges seem to be wider than the chassis rails.

If that is the case then presumably the diff has to be tilted sideways in order to extract it from the car.

That I find worrying, because I can't hardly pick up the spare diff I have, it is just too heavy for me.

Can anyone confirm whether the diff will drop straight through, or does it need to be guided out?
