Cone filter fitting and other things

[johnny]

Sorry about what must seem like more obvious questions, I have searched the forum but can't find the answers

First, how do I connect a cone filter in place of the original air box as there isn't a normal tube to use, is there something in the scrappies
to adapt it?

My speedo over reads by about 10 mph, is this normal or are the tyres likely to not be the original size, its on 15" 60 series.

Lastly, once the car is warmed up the tickover rises to around 1300 rpm, any ideas

Thanks.
