galaxie 500 rear
 

how hard would it be for me to put the 9" rear from a 72 galaxie 500 into my 67 coupe? also does anyone know if the front discs can be used in a GVM style conversion?

Rear end housing
 

I think the critical demension is the track width of the rear end housing. Contact Red. I seem to remember that he had a link to a web site that told what specific Ford models had rear end housings of different widths that would fit specific Mustangs.
