Hi All,
Thanks for the replies so far, I went out to the garage just now (needed some wood for a DIY project, that's another story) I lent over the back arches and pushed down and... nothing, I couldn't even push them down that much, like maybe a mm or two, I also got a photo...
Feeling the tyres don't help me as someone put pretty much brand new tyres on it, I have a trolley jack on order and some axl stands too once they're here I can get under it for a better look.
