Stop in for a cup of coffee
So made a paper pattern for fargo headliner from a photo off the internet,using an overhead projector. Then made a cardboard one. Then test fit it. Im thinking the 1/8 panelling i bought should work fine. It actually bends pretty well, but will need to remove seats to get it in place.
Went for a road test, cruise is better, i improved the ground, replaced disintegrating air filter and cleaned a contact inside the servo. Seems to work better. A tiny adjustment on engage control screw and it should be good.
