As far as not butchering the cowl it isn't possible putting a gasser on the narrow fuse of the Rascal 110 -- I just got mine mounted and have not cut the cowl -- waiting for my slimline pitts for it. But looksl like the right side will have a pretty descent size cutout for the carb assembly to stick out of -- and with the pitts looks like some small massaging will have to be done but the majority of the left side will stay intact.
