hi all, i have some ba fairmont ghia leather seats here which im planning on putting into my ba xt sedan. i took out the old rear seat with no issues, and put the top half of the rear seat in easy too. the issue im having is the bottom half of the rear seat. the positioning tabs are in a different place to the stock xt one. does anyone know if this is normal? or have i got a seat from a different car, possibly an au? or does the fairmont ghia ba have a different sheet metal interior? i thought all ba sedans excluding fairlanes and ltd would have the same sheetmetal work and and factory body holes in them, the difference being what parts get fitted to the shell? any help would be much appreciated
