Top of the Line Trim Package...
Ranger-XLT
(Top of the line from '70-'77 until that Ranger Lariat Package came out in '78...)
My dads '77 F-350 was a Custom.
Oh I just remembered,I swapped a GloveBox door from a Custom on him,so he says Custom on the GloveBox and Ranger-XLT on the bedside
What it looks like now:
I don't have a picture of the Interior Ranger-XLT Emblem on the door...(Which I think is really cool)
