TR4A sway bars installation information

["The Browns" <thebrown@scci.net>]

I'm planning to add sway (stabilizer) bars (front and rear) to my TR4A
solid (rigid) rear axle.  If anyone is familiar with this installation,
I would appreciate your input.  What did manufacturer, Vendor, bar
diameter, P/N, etc. would be helpful?  Since these bars were not
installed originally, nor offered as options by Triumph, I assume those
who have added them have adopted bars from other models of the TR
series.
