After phoning around I have found a supplier that will supply smallish quantities of Delrin at about £32 per metre for a 50mm diameter. They can also supply the glass filled delrin but he seems to think it may vary slightly in its composition to the stuff available in the States.
Therefore how much do I need to order to replace all the front end bushes on my 412, is the glass filled preferable, and what diameter rod do I need to order? They also have it available in sheets, would this be suitable for the donuts for the radius arms? If so what thickness?
I think I have also found the correct front end KYB GR2 shocks part number 365008. If someone can confirm this I would be grateful before I fork out and buy them.
What size of Delrin do I need to order?

Thats a bit pricey. I can get one foot of standard of 2" diameter for about $45 US including shipping. ....wait....32 pounds...about $65?...for a meter 
? Great deal!
You need about 9" to do the front. I would add about 4" to that so your machinist can have enough to play a little.....AND.....at the same time have him/her turn out a pair of new centering rings for you radiuse arms. You will love them and never have to change them again. Gets rid of tons of vibrations in the front end...stops the wear on the radiuse arms...and I can measure my new spares tonight and send you the specs in the morning.
While you are at it...pull one of your real trailing wishbones out...press out a bushing and have a set made for that as well. They will be similar if not identical to the front. If they are within a mm or two ...just have them made all the same and dress them with a file to fit.
The radius arm centering rings are critical. I had mine made back in 95 from delrin. Not a mark on them. Ray

Couldn't get one!
Actually I was in the market for a lightly used vehicle...because I just moved here when my rabbit dies...and had not established residency and financial details yet....so financing for a brand new car will be ugly until say...December.
It was not too hard to get into an 06 jetta with 55,000 miles. It looks and drives mint. Used TDI's in april were like gold...else Iwould have bought one.
That being said...the five cylinder engine is sweet. Even though the 06 is only 150 horse (the late 07/08 are 170 hp)...it gets up and hauls backside. I got one with a five speed. Nice gear ratios.
Its also because there were no TDI's shipped in 07 to teh US...due to afire in teh cylidner head factory.
Just read in the washinton post this past weekend that teh VW dealerships have just said that Jettas and rabbits with TDI will be available again in teh new model year starting September.
The article said that they are writing orders for more than they can ship...and have a waiting list. Love it!
No complaints though. By next year i will get out of the Jetta...into a rabbit with the same engine and drivetrain....and 400 lbs less weight.
The 2.5 five cylinder has gotten odd reviews. I have found that those doing the reviewing are bringing forth issues that are because (a) they do not know how to drive this engine and (b) they do not understand where the sound is coming from. One of teh complaints was the rough sound of the engine. It has a wicked exhaust system on it. If you know anything about engines....the first minute you drive it....you will realize that they went all out on the exhaust system. All stainless. very throaty and free revving.
The drive by wire and self diagnosing (fuzzy logic ) gas pedal system is a little odd. It tries to learn. It also is extremely light...as the motorized TB appears to suffer from a slight programmed sensitivity. It remembers the last driving style. If you have just been thrashing on it...and then slow down to sedate driving....the pedal is so sensitive that 1/32" will have you squeeching tires. Or...if you have bee ndriving sedately...and want to lay rubber....you have to reach for it. All in all it drives great but you have to learn a bit of what seems like turbo technique to pedal it right.Ray

Thanks for the link wshawn, I'll have to give them a call 
The Jetta sounds really sweet Ray, we don't get the 5 cylinder petrol engine over in Europe, just yet, I have heard they will be releasing a twin-charger version of it soon in the Audi TT. We do have lots of different TDIs though! I've had a soft spot for inline 5s since I replaced my 412 Variant, as my daily driver, with a 5 cylinder Audi. They do sound glorious, my friend commented that I had only bought it because it sounded like an old Volkswagen!
