Body panel issues

[j.brownster79]

Evening guys I may of made a boo boo I brought a nose cone, bonnet, scuttle, and arches from a guy that made a book spec frame apparently they are gts panels and have never been on a car! They don't seem to fit my book spec frame which has worried me now, can someone give me there nose cone measurements please? And position/ overhang? This nose cone when it sits on the frame it doesn't go anywhere near the bottom frame and when it does sit right back it's then not wide enough to cover the top side rails think I may of waisted some money here!!
