How feasible is it to replace a 617(84 300D turbo) with a 603(87 300TD)?Is this something that will involve major reconstruction of the engine bay and mounts,etc.Or is it something that can be done fairly easily.

It can and has been done, but there will be a lot of custom fabrication.

any sugestions on where I might find something resembling a "list" of that fab work?

1981 240d (engine donor 1983 240d) recently rebuilt engine hurray! - No more.. fought a tree and the tree won.

pearl black 1983 240d 4speed (Converted!@$$%) atleast the tranny was rebuilt.

I wouldn't mind doing this swap. Haven't found anyone who has done it, but I've seen a W123 that some Finns dropped a 606 into. No details, however.
