Just changed the damper oil on my fighters. According to the Pace website the air chamber side should also have 7.5ml of oil, but as far as I can see it does not tell you how / where to put it exactly. Do I unscrew the nut on the dropout again and put it in through there? Cheers

Yeah, that sounds right. I did my RC39s recently and just squirted a bit of oil in the bolt hole by the drop outs as I reassembled them, pretty sure that's what the instructions said.
