78 with v6 just got 2 weeks ago. Has been starting up fine but last couple of times it was a little difficult - turn key and nada except for dash light. Also seems a little more effort to turn key than there should be. After turning key a few times it started up just fine - yesterday I had to walk away for awhile but when I came back it started again right up. The wires on top are tight, just asking if someone might steer me in right direction before I start buying parts. With the key acting the way it is, I'm thinking maybe ing switch, key cyl or maybe starter. Now that I got it running, I can't wait to take it for a drive but I don't to get stuck somewhere. Any help please
