Axle replacement on 1972 Overlander

We're going to have to change the axles on our '72 Overlander, but we're trying to spread out the work to limit the cash flow "geysers". Can we change the axles after we're done with the inside? Would it be significantly easier to do if we had that one over-the-wheel floor panel out? How hard will it be to remove the old mounting bracket (assuming we need to?) from the frame?



Thanks!
