I'm dropping off the trailing arms tomorrow for vapour blasting. Those damn sensors were dogs to get out - I wish I had read the Rennlist article sooner - essentially just drill and hammer them out. I then had a similar issue with the metal sleeves for the rear bush of the trailing arm - man they didn't want to shift. Rennlist to the rescue again.

I used the hacksaw method with lots of WD40 and heat. 
 



Those trailing arm bushes were a real pain to get out - there isn't much rubber on them at all, a very rigid piece of rubber sandwiched between the inner and outer metal sleeves. I wish I'd not bothered now as they were such a pain to get out and then the replacement ones were about £45 each inc VAT. I don't think they wear much at all so they were probably still good. I went with original Porsche bushes which are actually available, you just have to be sneaky. If you look in PET they do not list a replacement bush for the aluminium trailing arms but the earlier steel trailing arm uses exactly the same bushing! So if you look in PET at the earlier steel trailing arm you will find the replacement bushes - part number PCG501541. They come in nice little Porsche branded boxes as well

That's great info re using the earlier model bushes. I had already bought the Powerflex bushes, which are actually poly outers with a metal inner - versus the steel outer/inner and rubber middle OEM. Regardless of quality, if someone is allowed to drive these cars in 30 years, they will have an easier job replacing those bushes!
Regarding PET I use it to search part numbers but how can you access current pricing without calling/emailing the OPC?

To access pricing you need the Price Update tool for PET - will send you a PM if I find anymore information to help you out.

If you go on Design 911‘a website and use the ”Fast Part Finder” it lists the price from Porsche. 


It’s usually a bit out of date and not quite accurate but is a ”near enough” to let you know whether something is worth buying or looking elsewhere for. 


Amusingly, you can also use it cross reference the parts on their own website to see just how much markup they’re adding!

I got the parts back from blasting. Everything is looking good and I have started to re-assemble with the bushes. I still have a few parts to buy and it's all adding up :( - it didn't help that I had a broken spring on my 997 so that was an unexpected cost replacing all 4 springs. I also got a surprise invoice today from Fedex for £65 duty for parts I bought from Mecatechnic back in January... I will have to rethink buying parts from Europe.
 
 I have started to clean up the rear wheel hubs in preparation for the new wheel bearings and the CV joints for the freshly painted driveshafts.

And I have removed the transmission cross member for blasting and painting, and I will rebuild the bush with polyurethane. Can I use any poly kit as long as it has a hardness of 60 - 70? 

It's all about making progress, however small, each week. I know a lot of you understand that. For whatever reason I decided to start at the bottom and get to the engine afterwards. I plan to have it back on the road for the summer, and get more miles driving it before looking at the engine.

Looking good - I used a poly kit from "Easy Composites" when I did my gearbox mount, I used their Xencast PX60 - Medium Flexible Polyurethane Rubber. I left the existing rubber in the mount and sealed it with gaffer tape, then filled all the cavities with the mixed solution. The result was really good and it is very firm.
 
I had my hubs vapour blasted (not sure if that was a good option), they now look very silver / aluminium coloured. I saw on youtube a guy refurbishing an old 911 and he used Owatrol oil to seal the metal on the hubs, so I've purchased a tin and will be painting them with it before refitting.
 
We both started in the same place - I'm hopefully putting my rear end back together soon, when I've finished painting the chassis. My engine rebuild is overdue though I think so I will be turning the car around in the garage once the rear is back together and start disassembling the engine. I'm leaving the fuel tank out as I will be sending the body shell off to a bodyshop to get my rear valance repaired with the section I bought last year and a new exhaust hanger fitted.
 
Looking forward to more updates

All those clean parts really press my buttons!!! Looking forward to some pics of them fitted!!!
IG racing really does go above and beyond ,he rebuilds and dynos every shock absorber,hes a real perfectionist!!
I wish i had the knowledge to strip a car apart and do something similar with mine,im thinking of getting mine Cryo blasted and Lanoguarded at some point,not as thorough i realise but within the realms of what i am capable of organising.
Keep those pics coming!
