I have a 1990 Bonneville with the LN3 3800. The lower intake manifold gasket is leaking again, so I am planning to redo the gasket and replace the intake manifold bolts as well. However, I cannot find the bolts online. I found some 3/8-16'' bolts on Summit but those are for the RWD 3.8. It seems the FWD 3800 bolts are nowhere to be found.
