MGB GT rot replacement - work order?

[Highspeed125]

Just about assembled all the new BMH panels to replace Floorpans, spring hangers, crossmember and all four sill sections. What is the best order of work? Sills first or last? Only have axle stands x 6 to support car, and not long reach ones either.
Sounds a daft question so I hope there's a short answer!

Hi Guys and many thanks for your replies. Unfortunately the project proved too daunting due to advanced chassis rail rot and I've now got a buyer. Another exciting MG project is looming so I'll be back with news when that happens.
