70 Swinger Dash lights

Well I will start out with a sorry for wasting your time. 2 questions: I need to change turn indicator lamp [right turn ] , and maybe the fuel and temp lamp. I have the ralley or sport dash. I am thinking the only way to do this is to remove, dash-cluster, that is what I have learned by searching.Has anyone done the lamp change differently ?? I have heard the speedometer cable disconnect is not friendly,,,,, then after that,, the wire harness is very stiff and short,,,,,also, if there is a lamp for radio, it is out too. Q-2. Turn signal flasher, [found 4 way super easy ] it says in book the turn flasher is by radio and wiper on some "rail" ,,,,,,Can't find it, even with it clicking,,,,,,I-carumbah !!! Any secret tricks to fix these things,,,,
