Help: Where can I find a good copy of Sangam (1964)

I’m going through Raj Kapoor’s filmography for his 100 year anniversary and am having trouble finding a good copy of Sangam to watch. The version on Zee5 is only 3h4m while the actual runtime of the film is 3h58. The version on Einthusan is 3h12m and is not very good quality. Anyone have a link to a better copy of the film in its original runtime? Thanks.
