Auxiliary Fuel Tank Parts Needed

[1-PU70]

Im looking for

1 - the 3 long carage bolts that hold the tank up I had to cut the heads of to get them off

2 - The 3 pieces that screw onto the bolts(holes must be square not rounded like mine

3 - The cover for the fill hoses.

Here is a pic of the 3 items.

Im also looking for the metal plate that screws to the floor around the fill hoses and the gasket that goes under it.

My tank has a sending unit in it. Are they still avalable?

Thanks Gary
