Re: starter wires
Paul, I don't think at least on both of my 69's, that the starter harness runs thru the wire gutter like Jim's pic shows. Maybe different on a 68. There just not long enough. They come straight back from starter, clip to bellhousing bolt and then run over top of bellhousing and come up by wiper motor. If yours are long enough, I would run thru gutter like Jim's pic shows. I'll be under car tomorrow if you want some pics of it.
