Do the cage when the body is off.
If you need to do it when the body is on, here's a way you can do it even with the car fully painted ( but no interior):
Jim Smith at Cotsweld did my last one and he has a nifty trick - he cuts out holes where the "feet" end up going and builds the cage inside the car. The bottoms of the uprights are stood on the workshop floor, poking through the floor Flintstones style. He easily gets to the tops of the upper tubes etc.
I'm sure others do this.
The final part is great - the cage is raised into position and the "feet"/baseplates are added last.
