rear axle alignment

[midniteblues]

seems to me me after swapping a 5 lug 72 rear in my 67 the axle looks 2 b offset favoring the driver side there is a 1 1/2 differance behind the inside of the back tire n the frame we have 3" drop blocks air shocks new standard coils and a adjusable track bar on it. i dont recall this differance when the six lug rear was in it does the shorter 72 axle have something to do with this? or is my track arm wrong? maybe someone has some great info on this matter been tryin to get this long time project on the road and this bugs me
