When I took the scuttle off I found some sound deadening on the back which was absolutely saturated. I decided to remove and discard it.
Worth making sure the windscreen sealing strip is secure and sealing the scuttle panel well on reassembly or you'll get water in the plug wells. 
Hi Kevin, I meant to ask earlier, what do I need to be looking for? The grey strip at the bottom of the windscreen seems sound but there are some areas of delamination on the windscreen that could suggest water ingress (I might well get a crack in my winscreen and need the services of autoglass at some point in the future

). I also noticed that the metal strip that houses the securing clips for the scuttle is looking pretty rotten

, this car might not be the one I was planning to keep on as a running classic, but I do plan to get a good few years out of her.
This weekend, dropped the ball joint and found the boots I'd ordered were too small

Cleaned, degreased and regreased the front caliper mounts and put new rubbers on the pins.
Fitted the PAS high pressure hose that I'd got from gstylebaby and was pleased to find the pre-facelift pipe fits a facelift, the only difference being the pre-facelift pipe does the job of two pipes on the facelift. I can only imagine GM changed it to two pipes because it was a complete bitch to manipulate at both ends!
Started rebuilding the front end with a new condenser and drier fitted. The Condenser was a pattern part and I'm not 100% happy with the joint between the condenser and the pipes on the car, but I'll have to let an aircon specialist look at that for me, it might be possible to use a shim to get a better fit.
