I have an old gray bodied Spyder that I stuck and e-frame on. I had no problems bolting it up. I adjusted the trigger and went on my way. I would think you would have to go though the same procedure. My e-frame came from an old Spyder imagine. I am not sure if there are any differences in the e-frames from one Spyder model to the next. I would give it a try before sending the parts to an air smith.
Instead of using PBN to ask your questions I would recommend
SEA or the
Spyder Forums.
