Perhaps PJB can correct me if I am wrong but I think that the seals (reversed to act as scrapers) could be added fairly easily when the springs are fitted regardless of the type of bush fitted. It may require pressing the lower bush in a little further and running the reamer through the bush to remove any distortion resulting from the pressing. This should help to exclude damaging grit from contaminating the grease and the bush and pin interface.
