Hi all,
`75 model. My manual doesn`t give instructions or vacuum values for
troubleshooting a sluggish headlight system. Right light is sluggish when
it works and the left light needs human assist for any up/down movement. It
does say that defective vacuum actuators can be removed thru the hole
created by removing decorative front grill. I don`t see how the things can
get past the large tubular vacuum tank. I hope I don`t have to remove the
hood to replace those items. TIA

I don`t have first-hand knowledge, but I do know there`s a book on the
subject; here`s links to a couple of articles, one of which references
that book:
