Thunder guy... Since you've taken a P-85 in to get bushed for your crank , you can either take him the jackshaft and your cat sec. and tell em to "make it work"... Or as stated earlier , Take steel shimstock and cut a piece ( probably 6 thou.) that wraps onto the shaft where the clutch rides ( stopping it at the keyway of course).. Then the stepped key is needed cuz the doo keeyway is larger than that of the keyway in the cat.
This one was taken to a buddy who built it up an re-cut it for the cat sec. then re-cut a new keyway slot... More expensive but if you know someone who's a machinist it shouldn't cost too much and you won't have to worry about changing out worn shimstock..
Once you get er on there , judging from your combination you wouldn't be too far off with using the following. Red with white stripe spring (middle position) , Straight 49-50 helix , and go from there.
