Has anyone ever done or have any advice as to how easy it is to relocate the springs to the inside of the frame as I need the clearance for my disc brakes. I am running a 52 inch Ford Granada 9 inch rear end and the old perch area is too close. Example: I was thinking of moving the gas tank to the centre which would mean I would need to remove the spare tire holder-no biggie-but has anyone done this or have a website that they could send me to. Thank you very much.
