Thanks again Rebel1, had seen another fill point when I had it at go-kart stage but had forgotten with the body on for so long now. Obviously should have done the
oil change back then. How often are you changing the diff
oil?
Engine is running the cast iron specials, forgotten the name, so no need for electrolysis worries, will have a look at the vintage air options. What did your heater cost?
Cheers
Steve
