Does anybody know the rear frame width of a 1969 Highboy. Im at college right now and the truck is back at my parents house so i cant really measure it myself. The local junkyard has the lmc chrome bumper 49-9898 for around 30 bucks. I say thats a great steal if that fits.

 

I believe rear frame rails are 33 1/2 inches apart through 1976 on F250 4X4's.

 

That would be 77 to serial number Y20,000 for F-250's according to ND.

 

These specs are from a '70 F250 4X4
Outside edge of R frame rail to outside edge of L frame rail is 34.02"

Center of right rear frame rail to center of left rear frame rail is 31.54"
