Oil cooler creeps slowly towards installation/completion -- one part off to get machined. Fitting the first stainless hose based on a youtube video, and surprisingly, the cutting method works well. I'll fill you all in later.
On the "mystery gasket" front, they were new exhaust gaskets for my exhaust. Almost secretive, the information regarding the Arrow Mini Twin Evo was hard to find. The system was never imported to North America; the Canadian Arrow distributor had never heard of it (and tried to sell me a standard Arrow system for twice the online price), and the US distributor was not interested in trying to get ahold of one for me. In the spirit of international commerce, I found one online from a UK shop, and purchased it. I won't go into details about the price, but if it is the system used by racers at the Isle of Man, it must be a quality piece.
The tracking information is always interesting to see -- from the UK to Canada (Toronto) in 36 hours, and from Toronto to Brandon in... 3 and a half days! Who cares, its here, and I have it installed. It's a pretty cool looking piece of kit!
