SSP gas assist

[WeberKell11]

I am in contact with the seller of an SSP that apparently has had the gas assist completely removed.  Just curious if my options for adding some sort of propane assist back to the unit are essentially wide open and whether or not some options are recommended over others.  Says he does NOT have the 5lb tank either so not necessarily married to that either.  Thanks in advance to all of you grate fellas.

Burner tubes, mounts, Regulators, and hoses are out there.  Best bet might be someone here with these or some of these in spare that might be willing to part with them.
