[52flthed]

Unfortunately they don’t reproduce those anymore. Carpenters used to be the one to do that and people like Chuck’s used to sell them. The mirror 5” heads are still available from United and on eBay new. However technically the 52 truck was a one -year -only deal and came with 6” round mirror heads. So the difficult part is going to be getting your mirror arm to attach to the hinge. Getting a mirror head and even fabricating a mirror arm isn’t that difficult. It’s the bracket that attaches to the hinge and arm that’s the issue.

Recently on eBay , however I’ve seen vintage clamp on peep mirrors that have larger heads. They seem nice. Alternatively if you could find some vintage Yankee or other NORS type of 5” mirror set up those would be more likely to find than a set of FOMOCO ones. Yankee mirrors used to have a simpler design for attaching to the door hinge, probably more easily reproduced than the OEM design. If you were to go that route.
