Bit of an update to report on:
Bough some Oil to get ready for startup.
Finished fitting the exhaust last night, so I now have my beloved RC40 1.7/8" full system installed. Really looks nice - kind of a little bigger than standard, but is understated enough to not draw attention to itself. Went together lovely and really makes the car start to look more complete. Just need one larger Clamp (ordered today) to seal the join from the link pipe to the rear section as it's a little too wide for the standard RC40 fitting kit now. Other than that it'll bolted up just fine and sits really nicely in the tunnel without hanging too low.

Took delivery from a good friend of Two 10 inch tyres for my reverse rims, thanks again.

The heater is now rebuilt fully, And now has the stereo hanging from it, I carefully marked out the casing and then used pop rivets making sure there was no danger if hitting the fan rotor or heater matrix. Needs tidying up and painting but other than that looks good, Just started to wire it up today too.

Also got some success with the top ball joint finally, Took it to a friends with a better vice than mine, Bit of swearing, some hammering and it soon loosened. So I can rebuild that joint and get the last hub on and built up. Front end's nearly done.
It's all coming together now, I'd be lying if I said I wasn't getting a bit excited by it all! Must get some carpets next.
