Removing the body from the frame

[JimmyFloyd]

What is the best way to remove the body from the frame on my 1970 blazer? I am going to need to replace the body mount bushings, as well as clean and paint the frame and underside of the body, and could use some extra space to do it in.

Here is how the blazer sits right now:



I believe I have about a 12-18 inches before the top will hit the rafters once I remove the old door opener (coming down anyways as I have a new/used one to replace it with.) Underneath the truck is a 4.5 foot grease pit, so I will be able to stand up without needing to jack the frame up.

There is no gas tank in the truck, and the exhaust ends before the axles (true duals) currently. What will I need to remove from the firewall area? I figure the brake lines, clutch linkage and accelerator linkage. is there anything else?

To lift it, what should I use to lift and support the body? I just have a singe jack at the moment, but might be able to borrow another one.

Will I need to brace it at all? I don't have a welder yet, so currently bracing would have to be done with wood.

Thanks for all the help. Aiming to get my truck drivable by june hopefully.
