Rob, I was reading an article on Porsche restoration and funnily enough, they did stress the point that once you've started there will be many unexpected issues that need to be dealt with.
Makes it all the harder when you are trying to do it all by yourself.
Can you buy these pieces to weld in, or do they need to be fabricated?
Chin up, as they say, it'll all come good!

I've got the new jacking mount from porsche no problem, but the hole needs to have a new piece of sheet steel cut and welded into it. It looks 'bad' but still doesn't warrent a whole new sill etc. That would be a mamoth task in comparison.

Been a while since the last update. The past few weeks have been pretty busy with work and other higher priorities so progress has been slow.... The good news is the repair/resealing/repainting of the underside of the chassis is now 95% complete. Its looking pretty good and I'm happy with the result :-)

Some images still show the original clutch line in place but *all* tunnel services have now been removed and will be replaced. (probably aeroquip for the clutch line)

The engine bay has been done too. Services going back in now.

Before refitting the new rear suspension I want all the routing for the clutch and fuel lines in place as I recon I'm going to need to add a few extra clips along the runs. This make take another 2 weeks tho given the amount of free time. Its coming along tho. One chip at a time :-)

Does anyone else read these threads and get scared at the thought of the true state of the underside of their car? I had quite a bit of bodywork done on mine last year and believe my car to be rot free but what if something is lurking in an unchecked crevice??!

I think you're safe provided the factory stonechip rubberised coating has not been compromised. The issue is, if it has you won't see anything as it eats away behind coating. Pretty much all the bits I've sorted have been around the many brackets and 'strong point' of the chassis where things are bolted to. An area I deffo would take a close look at tho is the metal work directly behind the jacking points. These areas can only be got too via the small holes in the posts. Get right in there and muck them out, really clean and see what you have. I'd be willing to bet there arn't many (uk based) that don't have holes through or bad corrosion here.

More progress....
I've installed the new clutch line. Instead of the porsche item ($$$) I've opted for a flexible line that is more than rated for the job. This is a PTFE bore with stainless braid. The braid has a very smooth clear abraisive resistant coating which means it won't chew everything it touches. The line is a single piece from MC to slave with no breaks. I've also had to add a few extra P clips along the route for additional support. (all stainless fittings)
This has enabled a far less convoluted route than the original porsche line. There are no troughs or peeks in the route that can collect air and make it difficult to bleed. Just a continously rising line from start to finish.

Great stuff, looks good enough to eat. Rivnuts galore?
Will be interesting to hear what the clutch feel is like with that length of hose. Probably fine, I'm sure I've seen this sort of thing on race/rally cars. This sort of setup would certainly make it easier to drop and refit the engine and gearbox on a C4, the clutch pipe gets right in the way. Though I would be tempted to make the straight length down the tunnel out of 1/4inch cupronikel/cunifer with appropriate metric flarenuts at each end.

Given the clutch is non assisted hydraulics, the pressures involved are very low. As you've said, this setup is used in many competition and kit cars so I'm not expecting any difference. I did consider a solid line for the main tunnel run but that introduced a union and for no advantage. I'm taking the same approach with the fuel lines. They're next :-)
>Rivnuts galore?
Yep all stainless fittings and well sealed in.

It's far from hi-tec. I borrowed an old gun and compressor from a mate of mine. It was just fine for what I wanted doing the underside (its pretty hard to mess that up) but I wouldn't want to do panels with it... but that may be down to the operator also.
