Challenger Door Install

Does anyone have advise on the best way to install doors on a 71 Challenger? We had to remove them for our body shop to place new skins on the rusted doors and the shop went out of business soon after we got the doors back. Trying to align the doors to allow for smooth installation of the bolts and to ensure that they align to close is a real ***** with these heavy doors. There must be a better way to do this, and so I am soliciting ideas from you all...

Thanks,
