70 Camaro tail light outer ring dimension???

[Riggs 74]

Does any one have the out ring dimension for the round 2nd gen tail lights. I am looking to buy a set of LED sequential tail lights for a 74 corvette resomod, since they don't offer them for the vette, I thought I would try some from a Camaro. A picture with a tape measure On them would sure be appreciated.

Thanks for any and all help given.
