Yes, I do think he bulked up, particularly in the thighs and trunk. (I do not believe his left arm could've been any bigger.)
Take a look at him in 1976; a good shot of him from the back is at 0:20 or 0:41: http://www.youtube.com/watch?v=7-VeBIal8TU
Classic case of middle age spread my man!
PS: 1976 would make Laver 38 yo in that video.
