Guys I'm a stickler for keeping my RL in some type of order that said it doesn't always work that way. I just got my RL back on the road after sitting for 8 months and was changing the oil. I had pulled the boost actuator to get easier access to the oil filter. Dropped one of the bolts down into the dark abyss of the car. I heard it hit the filter housing the silence. Looked for it but not luck . Anyway those bolts are not sold by GM unless you buy the boost actuator, just my luck .! So I thought I would try on the forums to see if anyone here may have a bolt laying around at home taking up or collecting dust. This is a slim chance but thought I would ask anyway.
