Lets see your tow mirrors. '69 K20 needs your ideas.

There is just nothing better than what GM put on these trucks. They put all the thought into these and offered options to cover the needs trucks were bought for. The 3-point styles came about as a safety improvement... to eliminate the total blind spot created by West Coast mirrors. Hence the name "Below Eyeline". Those are excellent mirrors and all a driver has to do is look fore and aft before pulling. Truckers do this to this day. The same as what you have to do with some of these fat A-pillars on newer trucks.

Any other mirror looks cheap, especially those generic Ford-style mirrors. I call those K-Mart mirrors. They were always the common I just need a mirror replacement.
