Frames for Mono and Crf style swing arms?

[pitboss125]

Just wondering if a mono and a crf style swing arm require different frames? i know they require different shocks, but will a crf style swing arm fit on a bike that origonally had a mono style?

Top shock mount may have to be modified in a lot of cases.

Top shock mount as Mack said will have to moved lower on the frame, you wanna make sure who ever does this for you knows there shit and puts it in the right position.
