Advice welcome... removing sliding door and door rail

Hello all,

Couldn't see anything previous on this topic - advise me if it's been covered somewhere already as I'm new to this!

Got a bit of rust happening where sliding door rail is bolted in to side panel. Smash repairer suggested removing and assessing how bad it is before bringing it in for repairs with him ($$). He said I'd need to remove sliding door to remove track. Looks like I'd also need to remove inside panels.

Looking for advice on this operation. Is it a massive undertaking for an amatuer?

Any advice/tips welcome!

Vehicle is an 89 SC 4wd.

Cheers.

No need to remove door. Remove internal trim undo nuts holding the rail. Remove the end stop on the our side. Open door fully. You can now wiggle the rail out. Refitting requires more of a jiggle to get the door roller into place and the threded studs into the place in the panels at the same time, oh it's fun!

Most show a staining of rust on the the paint work on the curved bit. Of course to get any spraying the door will have to come off - word of warning it is heavy!
