I have a set from a 68... don't know if they are the same. If you are interested, I will take pictures. Gil
Sorry guys, The 68 backing plates are different. They have a ribbed aluminum piece attached near the front, that the 69-70 pieces do not have. Duane
...and the area that the ribbed alum piece covers is inset so the alum piece sits flush. Someone needs to put a 68 chrome base behind a 16" armrest to see how well the armrest covers this feature. It may be that it is unnoticeable but I haven't checked. Patton
