Serpentine belt P/N

[hemi8]

What belt P/N are you using now that the TTA factory belt has been discontinued. I need a new belt but the GN belt is too long (same problem I ran into 4 yrs ago).

Part number for the belt is #1239983 and heard its discontinued. The size is 20.80mm wide adn 1603 inches long.

Oringinal replacement belt for GN/TTA is #10105307, but heard the GN is about 1/2" shorter might run into problems in the belt tensioner.
