-=Jeff=- · 3 Weeks Ago

When I went to do this on my 1990. I found the case hitting in a couple spots. the Later design Alternator uses a slightly bigger case which causes it to not fit. in my experience..

I would Like to see pictures of the one you installed, maybe when I did it I mised something..

I ended up upgrading my alternator internals and going with LEDs helps
