Hi Wolfie 1967, I need to replace my lowers on a '72 Marathon. I have seen plenty of videos on youtube and have decided to replace them myself. However, looking at the ball-joint press tools around ,I need to find out what their gaps ( between to open G- clamp part) are to be able to remove the joints. My son has a set ( unfortunately he is in the US) with a gap of about 8 inches. The ones I have seen on the internet are about 5 inches. Not sure this is wide enough. I'll let you know if I sort it. maybe you could let me know if you manage before me.
