I cannot figure out what is wrong. I swapped in A568 with OBX into my horizon. I'm using 88-90 auto axles out of the junkyard. With the engine all the way to the driver side I get about 1/2" of plung on the DS, on the PS I have barely 1/8". I have verified I am using the correct 525 tranny mount modified to fit the A568. I've compared the lengths of the 525 and 88-90 ps axles and they are the same length. I get full engagement into the transmission on both of the axles. I'm to the point of taking one of the shafts to the driveline shop and having it shortened. Looking for some advice on what I could check. Any info appreciated, thanks.
