Hi Mando,
as Phil says it is f/glass and being semetrical will always be a problem. My body is from the later body design and may vary a bit from yours & Mikes (not sure about Phils) and seems to be spot on. They do tend to settle a bit but 25mm is a lot. I fitted body and all fittings some 6mths ago and dismantled it all again for painting and putting parts back on recently and things did not line up as they earlier did. I think you might want to loosen of all hold down bolts and see if you and a friend can jig body around until yoy are happy with align. Did it come form CR fitted to chassis or have you had to drill holes in body etc.
ps/ dont bother with Mike spoke to him yesterday and he is working on his sun tan in nth QLD.
Cheers Leeroy
