Air Ride - which track bar/panhard bar

[Android04]

Good afternoon everyone. So I am in the process of installing all of my air ride and need to order my track bar. I was hoping to find one at the local swap meet this past weekend but didn't have any luck.

For everyone on air I've read that the longer the better so I was looking at the Classic Performance Trac Bars CP32021 or Classic Performance Trac Bars 6572DTBK. I was set on buying one of these but read some reviews that it doesn't work with air ride.

Any suggestions here would be great because I'm going to order it today.

EDIT: Truck is a 1965 SWB
