Proper way would be to put the chassis on a rotisserie, flip it upside down & do it standing. Or horizontal etc... Ideally, you'd grind the rail/floor to find all the spot welds to drill out & actually remove & replace the whole rail properly vs capping the rails like most people do.
But don't worry about doing it upside down... These things called welding helmets will prevent you from getting mig slag in the face  Now if you were under an aluminum boat with a tig the risk of a runny puddle does come into play |
I hate to tell you but I'm planning on just capping the rails as most people do. I'm looking for a little more structural soundness and peace of mind but my car isn't a great all around example of an s13 so I'm not trying for the complete restoration. Its a weekend racer and it beat on at the autocross course, not a pristine weekend warrior by any means.
I was planning on doing this all with the motor and trans still in the car. Hopefully that's fine.
Sounds like I'll have to get comfortable welding upside down. Urgh.
