Treat it as if you are chopping it but there is no chop.

At the back I'd cut it where finishing the metal work is the simplest. Probably though the rear window where you can also make yourself a gauge before you cut it to get it set exactly at the same height. The other way and maybe better is to split at the original seam.

Front and I hope Martinsr chimes in on this is to cut layers of the posts off at varying lengths so when you weld it back you weld the inner layer, then weld the outer layers. that way you have each layer welded individually rather than just welding the outside layer and no welds inside.
