The hi beams problem is probably the dimmer switch and the bushings in the wiper linkage need replaced pretty common problem .
Try bouncing your request off of Craig, otherwise known as FBBO member @mobilepartsNeed to ask all of you with a police special for some help. I have a 78 Fury police car. It was optioned out with the a38 package from what I can tell. I’m trying to get replacement bushings for the sway bar and struts. They don’t seem to be the same as a standard 78 Fury. What did you use? Thanks for any help.
