The Edge/RMK chaincase is longer than the Wedge chaincase. I assume you're doing a D&R? If so it will work fine. Be prepared to cut new holes for the drive shaft. Jackshaft can stay where it's at. You should try and find a rivet align template. This was a fairly common drop and roll that you're doing. The tunnel should work fine, be prepared to do some cutting/ trimming as required. Also build yourself something to protect the chaincase (bottom). The plumbing may need some tweaking as well, all easily doable. Good luck.
