I took that rear heater out last weekend. Removing ancient hoses was the hard part.
Maybe someone else could use some info.;
I removed the large "tee" fitting that is up against the firewall just right of center. I ended up lying on the engine to wrestle these hoses off.
I welded a disk of steel over the tube that serves the rear heater. I don't trust my weld to be water-tight so I soft-soldered all over the weld.
Replaced the tee and reconnected two hoses.
From the left rear of the block I removed the hose fitting. I think it was a 15/16" deep socket.
In its place I put in a 1/2 inch BSPT plug. I used telfon pipe dope instead of the tape. Plug available from McMaster-Carr.
I cut the rubber hoses under the truck and got the heater unit out.
I cut out a steel oval and epoxied it in place over the heater's pipe outlet. Painted with anti-rust gunk.
