Very nice mate, I've got one of them sitting in a box, I didn't know that Derale used a sleeve, but it's a good idea, and would keep the weight down, hell, I think I'll start using sleeves in my adapters from now on, it'll save me a bit of work too! I love the special oil filter canister, I wonder why they bothered though, apart from aesthetics, I can't see the point? Those Lockhart thermostatic bypasses are still available, not really necessary in warmer climes like Oz, but handy on the frozen end of the planet, for sure! Cheers, Terry.
