Thanks for techinfo
Thanks to the people who do Techinfo. I used the one for accessory belts. The pictures help. In this case thanks to danthurs. I used his info and all I could read in other people'* posts.
I changed my 1998 leSabre serpentine belt. Most people had trouble with getting the spacer back in. I was all prepared to give it a bump like the other people had reported. When I placed it with the bevel at the right angle to bump it from above, it slipped right in with my finger pressure from below. I did have to tap it to force it up and out when I took it apart.
I posted here so others know it'* not always hard to get the spacer back in and that would help the next guy or gal doing the belt change.
