Fitted the Monza last night and finished off in lunchtime today. I planned to fit the rear brake pads / discs at the same time but since I'm fitting braided lines and need the car tonight, that wasn't practical.
Decided to take the rear bumper off since it makes swapping back boxes easier (easier to get to the mounts and gives you more wiggle room if the tailpipes aren't hitting the splitter) and I wanted to do some investigation around the rear wheelarches and stick some more rustproofing in, so out came the wheelarches, off came the tail lights (remarkably filthy in their aperture) and off came the bumper.
Rear wheelarch (minus spiders):
Nothing too scary in the rear wheelarches (unless you don't like spiders - there were loads of cobwebs behind my wheelarch liners) but where the bumper attaches to the corner of the rear wheearch there is a double-skinned area (much like any other car at that point) so will have to stick some waxoyl in that corner when the rear trim's out to prevent any future issues.
Possible rust trap:
I spent some time researching a lubricant with v high heat resistance for the Monza's valve, and found out the one I use for almost everything is the best (copperease) - it has a 1500c limit
So diluted some with a little white spirit, smeared it over the spring-loaded hinge and allowed it to trickle in whilst working it back and forth. It wasn't bad to begin with but now it's 'as new' smooth as it operates.
Then stuck a load of waxoyl in any exposed nooks and crannies and a nice covering over the paintwork inside the wheelarch liners, and all back together.
Off with the old (look at those filthy indicator apertures!):
And on with the new(ish):
Sounds nice to me:
