Mine is a 70 not a 69 but these are 17x9.5 with 5.5 backspace. Tires are 275-60-17, 9 3/4" across the tread and 29.98 tall. That's as big as I can get in a Plymouth wheel well. There is also a 3/4" solid steel spacer in front of the leaf spring perch to push the rear back to add clearance at the front of the 1/4 panels.
