Yeah definatly the first shot of your Cobra that would be an ADR breach and a red sticker job.
I had some problems with bolted joints in my old 4WD Patrol project and two books that helped me alot were:
High Perfomance Hardware

Carroll Smith's Nuts, Bolts and Fasteners and Plumbing Handbook
http://www.amazon.com/exec/obidos/tg...glance&s=books
The new ones look nice.
I guess I should get my hands on a colour book of ACs so I can see what they looked like and what the differences between the models were. You blokes got any ideas?
