fitting SC alternator in early car
 

guys;
the car is a '69E. it was already fitted with an internally regulated Paris-Rhone and i don't recall this being an issue. that unit is no longer available to me. onward... the replacement works fine BUT it is longer than the other unit such that the 2 pullies are no longer in plane. i presume my options are;
1) upgrade to a later housing or;
2) mill the existing housing to fit.
if (1) which years do the trick and are there any other considerations ? if (2) then does anyone know the exact amount of material to remove ?
any other options ?
thanks all.
cheers
jerry... starting to chomp at the bit.

Jerry,

The 1975 and later housings were machined 9.3 mm deeper to accept the 980 Watt alternator's case. The replacement doesn't have to be a Valeo or Paris-Rhone -- the more reliable Marchal/Motorola 980 Watt with separate regulator works, too, and is a better choice!

When we play 911 Trivia, I want to be on Warren's team.

count me in! this isn't the first time Warren has come to my rescue. the tip re: outboard regulators is well taken and not the first time i've heard it mentioed. one more piece of trivia ? my understanding is that there is some difference between the units mentioned above and the Bosch units. can "someone" outline that difference from the standpoint of interchangability ? ;-)
thanks again!
best
jerry
