Hello Peter
Looking at the picture of the winch you can buy. Yes that looks a lot less work than re working the heavily modified one. However is the whole chassis that the [summer] winch is in for sale? maybe not to daft an idea to use that rolling frame as a Basis for the rebuild and use the best parts of the two chassis to give a straight forward project At the very least just use the frame and add your own Cab, Engine ,Transmission Springs and Axles.
In this scenario providing they are both Chev You can Overhaul A complete Axle and suspension off your original unit and after Sandblasting summer frame just re assemble the Reconditioned units.,straight onto it.
Once you have a fully rebuilt truck you will have a pile of Used items that someone else may wish to take on Without the hassle of removing them!
Whatever you decide to do all the best
