i just discovered that when i sent my 62 impala factory tach off to be repaired it came back with the wrong face plate. the one on it has no redline marked. the bad part is it took me years to realize it is the wrong face plate. i can find 62 corvette face plates but not 62 impala ones. my question is, are the corvette and the impala ones the same? if not , how much difference is there. thanks for any info.

There are 3 face plates on Sun Tachs with sending units sold by GM with 61 & 62 Chevrolets.
61 chevys with a factory Sun Tach did not have a redline.
In 62 there were 2 faces - a 5200 RPM redline used on 327/300 HP motors and a 6200 RPM redline used on 380 HP and 409 HP - 409 motors

There is no such thing as a corvette tach face for 62 or 61 Chevys on Sun tachs and the sending units by GM.

i copied and pasted an item on ebay. it looks like i could use it for my 62. originally it did have the 327/300. i have owned it since 1965 and the 327 is long gone but i do want to keep the interior as original as possible. i am probably going to buy this and see if i can make it work.

Corvettes did not come with Sun Tachs like those in my pictures. Corvette tachs were mounted in the
dash.
So that face will not fit a Sun Tach, it’s too large.

You can purchase tach faces like the one in my pictures for Sun factory tachs.

Here is the correct red tach metal face for a Sun Tach with a 327/300 HP. It mounts with 3 small screws to the tach housing after removing the chrome face on the tach.

Also, ALLLLLLLLLLLLLLL 53-74 Corvette tachs were MECHANICAL and were cable driven ------------- depending on engine -------------by either the generator, or the distributor.
