To fit a saph, escort or granada of arb to a 3 door, You have to weld mounting blocks to the chassis member at the rear to mount the arb brackets and you use the saph drop links and weld mounts to your rear arms to suit to fit it on a 3 door, really easy job to be fair, I fitted a 21mm granada one to my 3 door (rep) project

Pictures speak a thousand words

This is what I made to mount the arb bracket on, i made them from one piece of steel cut then bent and the corners welded together, then cut the flanges off, cut a slot in for the arb bracket then drilled a hole and weld a captive nut inside


This is the location of the arb bracket mounting blocks, this is before I painted everything up


This is the bracket I made to weld to the arm to mount the drop link



You can make out the location of the brackets to bolt the drop links to on this picture


If your using sapphire arms with arb mounts ignore the last part
