They LOOK very similar to these BUT are
CHROME finish not just polished aluminum. Definately much prettier than polished aluminum and far less likely to stain.

searching Summit or Jegs the 0397-M-6582-R460 no longer comes up so I'm assuming it has either been discontinued or there has been a part # change.
I paid $276.00 + shipping I'm asking $250.00 including shipping lower 48 states.
Still in box with original foam wrap protection.
