sleepn_sn95 okay. I got the measurements of my inserts. I took the insert measurement and not the bumper lettering measurement because the inserts are smaller than the bumper letters.
The only ones that really matter are these two measurements, because the font will stay proportionate length and width.
Each letter is exactly 1 1/8" tall. And from the beginning of the M, through USTANG G and to the end of T it is 27 1/4" long
The rest of the measurments I grabbed where more rushed. So they're more estimates than anything.
M - 2 13/16"
U - 2 1/2"
S - 2 3/4"
T - 2 3/4"
A - 2 1/2"
N - 2 3/8"
G - 2 3/8"
I literally went outside in the rain with a measuring tape and my phone and took pictures of the measurements and then wrote them down. I only spent time on the height and total length of the inserts.
Note: I have 'MUSTANG GT' so if you have a 'Mustang' bumper the length will be incorrect. And the GT letters are the same size as the G and T in 'Mustang'
Hope this helps
