I have two extra pairs of swedge tube. They all have some marring on the powder coat to varying degrees, but they should all still be usable.

One pair of 16" long 5/8-18 LH and RH threaded, 0.875" OD swedge tube ALL57366

One pair of 16" long 3/4-18 LH and RH threaded, 1" OD swedge tube ALL57466

both are listed as .160" wall tubing made from DOM 1026 alloy mild steel, but the 5/8th's .875" tubing is also listed as being "chromoly." So, not sure on that one. A lot of misprints on Allstar performance's website. I would just safely assume they are mild steel.

$35 a pair + shipping
