You have 3 easy options:

1. Buy a new pulsation damper

2. Get an 89-91 rail

3. Replace the pulsation damper with a bolt.

bad part was had to pull upper intake

that plug method sounds good to me/with locktite the dam screw could fall out going down road-on long trip- if we have any more trouble out of new one-its gone one way or another https://www.nopistons.com/forums/pub...>/rolleyes.gif
