yeh the rubber boot under the carpet..

Transmission Tunnel
Suit 1200 with SR20 or CA18 Gearbox. Comes with rubber gear stick boot.
Note: fitment requires removal of heater box

I have fitted the maddat tunnel but obviously it was purchased long before the new owners..

anyone know a good rubber boot that will fit well with the ca18 shifter?

Are you talking about the rubber boot that sits under the carpet? You will need to get a custom carpet trimmed up for that tunnel. Your trimmer will sort it out and put a nice shifter boot over what ever you fit up..

It depends on the hole you (or the person who installed it) cut into the tunnel.

Just curious as to what shifter boot everyone is using for the maddat tunnel? I contacted Maddat a while back and never got a reply.... I have a ca18 top and bottom shifter boot but obviously being round and the tunnel not being round it doesn't bolt up and or screw in very well..looks shiat...

I am hoping someone can point me in the right direction for best fitment and or what gearbox boot to use with my maddat tunnel?

many thanls
