Roll cage fitting advice?

[Nobby]

Hi guys right i have a 6 point cage im currently fitting to my Nova. Now ive welded in the rear spreader plates and box sectioned the rear of the floor but where the rear legs need to bolt to is about 15mm away from the spreader plates so obviously wont bolt up true. Has anyone else had these problems i know my car has had a NSR 1/4panel on so has had some accident damage before. Heres the pics -

Maybe it is not sitting at the back because your box section is too high.

Hi mate i cant get my box section to sit any lower? its 3mm steel and sits flush onto the outer part of the inner sill area?

You could all way box the back ones to meet the legs. Have you tried it with the full cage in as it can make a difference ?.
