My 84SD speedo reads low and it would be nice to correct it. I think that the 84 & 85 SDs have an electronic speedo but different trans ratios. I can find out the rear end ratios by rotating 1 wheel and counting drive shaft revolutions but don't know what was originally installed in the 98.
all turbodiesel 123's have the 3.07 ratio, except the 85 which got the 2.88

same years for the SD's but include the older 78-81 in the turbodiesel mix on SD's... 3.07

as for body panels... everything is the same on the wagons. glass too! interior parts change between years, so keep an eye on that. materials, headrest styles, etc...
