Im slowly working on the 360CS with MSM set and Acustion, trying to test fit the P/E parts to the body, and the resin replacement parts to the interior. There is a lot of parts in the MSM set, is well worth the money. Have been tied up at work recently, so progress is real slow, may post pics/thread soon.. So far all the parts fit togehter nicely, hope this helps.
While on the subject of detailed Ferrari's I would love to see someone to build this,
