My '53 Manhattan inside mirror is getting ratty, and I was casting about for a replacement. Did see on a couple of interchange lists over the decades that 50's Chevrolet mirrors are the same, at least for the non day/night. Looked for mirrors for sale on ebay for 50's chev, and discovered that the 53-55 models use a mirror that appeared from the pix to be identical to the one in my car. They were at some point remanufactured and some new ones were for sale by several vendors. Checked the thread on the shaft with the seller, and as it was correct I ordered one. Came today and it is totally identical to the one on my car, down to the "guide" on the tab. They sell for around $50, so anyone looking to upgrade the front seat area might go this route. Not sure how many are around any more- the guy I bought from has 3 left.
