Prep for repairing rockers and Cab Corners

[blkcorvair]

I am about to start cutting my rockers, outer floors, cab corners, inner cab corners and cab mounts.

Id like to do one side at a time without removing the cab from the truck.

Any advise on what thinhs should be disconnected to jack up each side of the cab? Also where do I start? Cab mounts first maybe and than cut everything else out? Than Corners than Rockers, Than outer floor? Inner rockers? Been reading alot of past threads. Seems I should have something to line everything up to. So thinking replacing the Cab Mounts before I remove all the Rusted Sheetmetal may be Ideal?

I need some suggestions. Thanks!
