Have looked around at a number of sites/posts on the location of the buttons for the '68 deluxe interior.
Numbers range from 4" to 4 7/8" down from the welt seam between bolster and insert to the top of the buttons.
Anyone have a definitive and consistently repeated location, or did it vary as noted by measurements to "original" seats noted in the in the various posts I have found?
Have a custom made TMI set with OEM SMS provided comfort weave and only want to punch the holes once, and hopefully in the right place...!
