Can a YF60 (quad) be turned into a YT60

[200XMichigan]

A guy has two YF60 for sale, haven't looked at them yet. Just wondering how much of the part are the same. Has anyone turned a YF60 into a trike. Just to point out I know you "can" with welding and fabricating but what I am asking is were the frames and engines similar enough I could buy a fork and frame on ebay and have a YT60 and a YF60.

All you need is the yt-60 frame and forks . The rest of the yf-60 4 zinger is the same .
