[Happy Wanderer]

Hi all, this might sound like a silly question but I'm trying to get my 75 up high enough to crawl underneath & work. I have big thick wooden blocks waiting to rest it on but what I need to know is, is there a central jacking point for the front & rear that I can use my bottle jack on?
I don't want to do one corner at a time as its already on axle stands & don't want it falling off them & there's no way of fitting the wheels on at the moment. I'm after getting the body about 2ft off the ground so I have room to work. Thanks in advance ������
