I've put the shell on its dolly ready to remove the suspension etc.

I'm on the UK old Porsche forum, DDK: www.ddk-online.com . It's a great community in many ways, and in this case a fellow DDK-er helped me out by letting me have the DDK Heritage Dolly when he'd finished with it. I believe it's 10 years old and has seen a few interesting cars.

Provenance is everything, of course. The DDK Heritage Dolly has mystical ancient markings... so at least I know it's been welded up by someone who knows what they're doing. 
Hopefully the car won't fall on my head.
Thanks Jamie for the dolly (and delivery service).
