Lugnut: So I finally found a super charger for Ropers Limo. I sent Dogbreath and his crew over to Gorge Junkyard and they hit the jackpot. They even found an engine hoist, some big block double hump heads and pistons. The head gaskets are blown but that shouldn't be a problem, I'll know more when I start ripping it apart. I'm also gonna take a shot at modifying the exhaust and suspension. The big rig is next on the list, though. I'm having spikes welded on to the sides, that should save bullets when dealing with ghouls. I just finished up mounting a harpoon gun on the hood. Can't wait to own some Settlers with that thing. The Radicals will rain hell on this earth once these vehicles hit the road.
