    Hey all, This is in regards to my 1986 FWB 307. My gasket for the top of the carb (airhorn) seems to be soaked (probably gasoline)..nothing that is dripping from it, but just soggy..easily tear-able. I tightened up the screws for the top of the carb (airhorn), which were loose. I want to...

    RWD 19xx-1984 DeVille and Fleetwood,1985-1996 Flee
    How could you get a VIN "9" engine from the factory anyways? They're not listed in any of the brochures I have, but I've seen them from time to time. Were they a silent part of that Trailer Towing Package?

    RWD 19xx-1984 DeVille and Fleetwood,1985-1996 Flee
    Anyone know where I can purchase one for the 307 on my 89 Brougham? It seems GM has discontinued this part. I can get one from a junk yard down the road but would rather buy new if possible. The GM part number is 17111104 I believe.
