Re: Question for the guys with OEM 71-72 sport mirrors
Agree with Lee H. That is the best way to adjust your mirrors. You don't need to see your quarter panel, and that area is covered by your inside mirror anyway. It takes a bit of getting used to, but as Lee says, having the mirrors adjusted out virtually eliminates blind spots, if you use your inside mirror too.

I was disappointed when I first started reading this thread because those were the mirrors that I planned on installing, but I thought people were complaining that they couldn't open them up far enough, but after learning the opposite, these might be pefect for me! lol. I'd really like to hear from someone that has these, adjust them as described above and see how you like them. Be warned, it feels like your shoes are on the wrong feet at first, lol.

Re: Question for the guys with OEM 71-72 sport mirrors
Just to confirm, are we talking about only the passenger side as having the visibility issue?

Re: Question for the guys with OEM 71-72 sport mirrors
I have several sets of these over the years and never had a problem, right now I have a set of NOS mirrors on my truck and I can adjust the pass side to see the bedside.However I did help a buddy of mine put on a set of repops on his truck and installed them back in the factory holes and it would not adjust in far enough, same problem as described....I blamed it on the repops.

Re: Question for the guys with OEM 71-72 sport mirrors
Hello to all,
Recentlly installed sport mirrors. They work fine. Used 67/72 Factory Assembly Instruction Manual. Found page with dimension's for locating sport mirror's. Dimension's are off of "reference lines" 20 and 35. Used another section of manual to understand location of "reference lines". Also passenger side is located slighty further to the back then driver side. Hope this helps. Serge |

I don't want to have to lean half way across the truck to see out of the mirror. I've been told the OEM mirrors aren't any better. I would even consider installing a round mirror on the sport mirror base if it allows me to see without leaning across the truck. |

You can do a search and find posts describing where the mirror is mounted from the factory. In these posts you will find pics and measurements. |

Re: Question for the guys with OEM 71-72 sport mirrors
Before mounting our repop mirrors in the factory location (which is where we ended up drilling the holes anyway), my wife and I took turns holding the mirrors in various locations and seeing what we could see. The driver's side is perfectly fine. Not so much on the passenger side, but there's nowhere you can mount it that makes it work better than the factory location. Someone - can't remember who - advertises a 71/72 passenger sport mirror with an actual convex lens. May try to find this again and replace the passenger side, because that would work pretty well.

Re: Question for the guys with OEM 71-72 sport mirrors
I guess I was too subtle, hope this exchange does not offend anyone. GM designed these mirrors to view into the blind spot. The blind spot is in the adjacent lane, just to the side and slightly lagging the vehicle. If you can see the rear quarter the blind spot is not covered.
The “lean” is only for adjustment to place the mirror view in the blind spot. Once adjusted, the view from the mirror is in the blind spot when looking from the drivers seat sitting straight, not leaning. So, if you want to see the quarter panel VS the blind spot, the sport mirror is not the right mirror. Peace, Lee

I've put some thought into this over the years, and this is what I'd come up with if I had the resources to reproduce. jlaird/josh@replicate.... if you are thinking about reproducing. I have some suggestiions: 1) Design based off the appearance of the 1972 factory sport mirrors. Keep the mounting base the exact same for a drop in replacement. You'll get way more sales. I'd buy 3 pairs instantly to replace my factory/repro sets. 2) Lengthen the mirror arm another 2 inches or so. 3) By extending the arm length, it will effectively raise the mirror, so you may need to vertically reduce the angle to reposition mirror to its correct spot. 4) By extending the arm, it will also position the mirror more reward relative to the vehicle. Again, an angle adjustment horizontally would be required. 5) Increase the size of the viewable mirror maybe by 3/4 inch height, and 1 inch width. This will help us higher 4x4 guys have more viewing area, without taking away from factory look. I'm sure 2wd guys may not mind either (maybe even 2 mirror size options). 6) Where the "mirror" mounts to "arm", add another 1/4 - 3/8" distance of separation , so that the mirror has more adjustabililty before the mirror edge makes contact with the arm (common problem on passenger side mirror) 7) Another thing I would like to see is a small blind spot morror build specifically for these sport mirrors. Small, square, all polished or chrome, and low profile. Something that looks stealth and not out of place. I like blind spot mirrors to see my rear tires against a curb when parking. Get some of these out quick.... I need some! =) Thanks much

Re: Question for the guys with OEM 71-72 sport mirrors
I put on aftermarket sport mirrors and had to do this to adjust the passenger side in enough to see. Not hard to do at all.

Re: Question for the guys with OEM 71-72 sport mirrors
I guess I got lucky. I bought a set of repop mirrors with the passenger side a convex mirror. I don't have an issue seeing down the side of my truck and the other lane. I'll admit not as good as the factory mirrors it came with but with the excellent visibility thru the back window I feel secure driving.
Now if I had a camper on it or towing a large trailer, better mirrors would be a must.

I had a set of the west coast jr on my 68 and nearly got creamed when I pulled out of a spot and a car came out of the blind spot created by those mirrors. They were too big for a pickup, my opinion. I put the sport mirrors on and have no trouble with either side. Those of you that are having the viewing problem, I read maybe on here, that a fellow took and used a rotary tool and carefully ground a little bit off of the mirror arm to allow the mirror head to turn in further. I don't think it would take too much to make it work. If you have the mirror already it would be worth a try. My $0.02 worth. Have a good one and good luck.

Re: Question for the guys with OEM 71-72 sport mirrors
Was not happy with my re-pop mirrors! I taper ground the bace, spaced the mount and die ground the retainer. It works.

I am looking for a passenger side spot if anyone wants to sell one.

Re: Question for the guys with OEM 71-72 sport mirrors
Reviving an old thread I started….. with a new question- has anyone found a usable mirror that has the same mounting hole pattern as the 71-72 sport mirrors? I don’t want to drill new holes but I do want a new mirror. Someone mentioned they bought sport mirrors that had a convex mirror on the passenger side, this would be a good solution as well. Who sells these? Thanks.

Re: Question for the guys with OEM 71-72 sport mirrors
I know LMC has convex ones: https://www.lmctruck.com/1967-72-che...n-door-mirrors, part # 38-5851, which I believe are just United Pacific C707202.

Re: Question for the guys with OEM 71-72 sport mirrors
I've got aftermarket mirrors. Not repops, they're 4" round actually. Same problem with the passenger side, can't turn it in enough to be of any use at all. I even played with it's position before installing it and it just wouldn't give me the field of view I needed.
I installed it and spent a couple bucks on a stick-on 3" plastic convex mirror and it actually works pretty good. At least now I can see in the next lane to change lanes or back through my very narrow gate if I need to.
