Will an E36 Compact roll cage fit in a E46 Compact

[OzE46]

Hi guys,

I'm building an E46 325ti club rally car and chasing a bolt in roll cage.

Bond Roll Bars here in Australia recently built a bolt in roll cage for another competitor for his E36 Compact which he is very happy with.

I'm hoping my car can use this same roll cage kit but I thought I would ask you guys the question....

How different is an E36 compact floor / rear suspension pick up points etc vs the 2002 E46 compact??

I need the cage to meet the CAMS (Australian version of MSA) spec and nobody makes an off the shelf kit for the E46 Compact shell.

Any ideas????

Thanks
