Everything went smoothly, for once
I ended up taking the Driveshaft to a more reputable company that just happened to be 10 mins from work rather than 35mins!
I cant recommend the guys at Driveline Services any higher, I know for you guys & gals in the States that might not mean much, but I was blown away by they're willingness to do the job, service and quite amazingly, price ! lol!
There was a little hick up when the guys finally saw the shaft and DC joint sitting next to each other. They had'nt planned on a cut'n'shut operation for this and thought it would be relatively quick. Oh well, goof thing they are a fully fleged machine shop. We couldnt use the original slip yoke and had to bin it in favour of a completely custom spun up slip joint with flange end. They made it 5mm longer just in case.
The stock harmonic balancer is unbelievably heavy - it feels like lead, the new complete shaft is definately lighter too, good for spinning mass.
It fit like a taylored glove and drives beautifully. At the moment i've only got my stock rear springs in so there isnt really any vibration at the moment (new Fr & Re custom coils arrive Monday) so I cant comment to strongly on how much better it is, but I know its is
Didnt realise this till I posted but you can also see the exhaust mod/change I did a few weeks back. The new tubes are above the chassis line and we also managed to get the cat up a bit higher in the process. The ONLY reason for thise mod was clearance. The noise change is minimal - un-noticable in the car but slight increase in noise outside, put it this was, the missus never noticed
