I am getting ready to cut the rust out of my 110... but before I do that, i want to replace my auto tranny so I can actually move the car around when I need to...

the front frame rails are there, but I'm not super confident to use them as a jack point... can I use the outside frame rails underneath the doors? is this safe?

rust is floorboards and front rails.. that's it..

in the back.. is the axle ok to put jacks under?

thanks!
