Dick sent me an article but it's also published here (with comments / feedback from others).
I can't seem to paste the weblink, but if you search the Forum for Mangusta Handling Mystery by Dick it's all there including photos.
If you are into upgrades I had a quicker steering rack made here in UK by a race company to fit (with a tiny bit of fabrication) which provides much faster response without making steering too heavy . About 2.5 turns lock to lock but they can make it to any ration you want. I own the design drawing but your welcome to use it if you want. I paid £500 plus shipping.
Cheers
