Yeah, I did. Parts for the conversion aren't expensive. I personally found it a right bitch of a job to do and wouldn't want to do it again! Details of whats needed are here http://www.apracing.com/info/info.as...difications_90

I've not heard of an ahmed cover before so I would call AP in order to find out exactly what you have. I found them really helpful on the phone. Best number for them is; 02476 639 595.
