K20 to a C10 and I need a vowel

[NurseBen]

Sold my '63 K20 and pick up this '69 CST from an ex-con that had been sitting for 15 years (length of his incarceration). So far I've lowered it with drop spindles/disks/coils in the front and block and springs in the rear. Wheel Vintiques with skinny bias ply tires in the front and MT 30x12 in the rear, never thought I'd enjoy a lowered truck but this has been my favorite vehicle to date. I need some help locating the letter "E" that is on the tail gate, I have the L it's just not on in the pictures. Thank you for the help.
Sorry for all the sideways photos
