1968 VACUUM BOOSTER

[124bernie]

Can anyone tell me which years are interchangable for avacuum booster on my 1968 Fiat 124 Spider.
I know there was a change somewhere around that year, but don't know which other years might work.
Thanks!

any year will work, the only difference is the check valve, the early ones were inline and the late ones are the 90 degree valve that goes into the booster, the early ones used a banjo bolt there.
