Funny thing is, the cb500t didn't come with fork gaiters so there may be no way to secure the ends of the gaiters on the 500t front end. Except for the handlebar mounts the triple trees on the 500 twin and 500 four were almost identical. All of the CB450 and CB500 twins 65 to 76, and all of the CB500 and CB550 fours used the same steering head bearings. Putting a 500t front end into a 500 four or vice versa should be a direct swap.
