If the mirrors don't sit in the exact right position there is a bit of fun with the mirrors , the Silverado Utes must have lower seats I suspect .
Overall the better vision you get is so much ahead of OEM plus a caravan mirror because of the blind spot mirror .
No trouble backing in tight car parks and can get to within 50mm of the trig hitch on the camper every time .
Because I've made my brackets completely out of steel I can pack out the tension spring with washers if vibrations become an issue , at the moment I think there about the same as the OEM mirrors as far as that goes .
Yes blind spot mirrors can be moved out as far as they go which leaves them sticking out but don't think it's a problem , passenger side won't fold back against the car if I hit something because of the snorkel and this could be an issue on tight tracks .

Finally got around to making the outer shape for these Silverado mirrors. Been raining a lot here so easy to justify the shed time.
I’m making it all from 3mm aluminium and so far it’s coming together as planned.

Hope the ally doesn't develop stress cracks in use mate .

They’re only a decorative cover so there’s absolutely no stress on it. The mirrors barely rub against it when you fold them.
I have Tig welded parts on my engine and in my engine bay that are subjected to much more heat, stress and vibration with no issue at all.

Ahhh ok so that outer is just a pretty up ,cosmetic .
The first person to do one out of alloy welded the bracket onto the plate but I notice your castings are better than mine , stress cracks mainly come from overheating during welding although ally can be annealed to reduce any stress .
As you've said though yours is cosmetic and your welds are good so no excess heat , if the rest of your welds are like that no you shouldn't have any problems .
Heard of a process in aircraft aly ,after welding the area gets a quick hit with a carbonising acetylene flame then gently heated till the carbon disappears.

The original cast alloy block is pretty thin and is probably the weakest part of the whole assembly. I welded 5mm walls inside the cast before welding it to the alu triangle. I've also drilled and tapped the 5mm bolt threads to 6 mm but I'm toying with the idea of drilling right through and passing countersunk 6 mm bolts from the rear of the triangle and using nuts for the bridge that holds the mirror against the cast.

I think what you've done is probably good enough , bearing in mind those mirrors are very heavy and if you consider the weight that's pulling down then magnify that by going over corrigations etc it's quite a lot .
Your casting is better than mine like I said which is why I went steel instead .
I've checked my anchor points / fasteners and they're still tight and after the tracks I've been on earlier in the year I'm satisfied they're not going anywhere.

This is the final result with the covers made from 3mm aluminium. The rear round section is a length of 100mm ally tube cut down the middle for each side.
Still need to make the gaskets from sikaflex.

Well done and very neat so congrats you've saved probably $500 on what the clearview would cost .
