I LOVE when I'm a complete idiot (happens quite often)....after looking at the picture above, I was wondering how the new sensor would fit into the SYE plug when the top of the shafts are different.
At some point after my build was quoted, the shop switched from a JB Conversion SYE to the Teraflex model (probably because of availability...and didn't charge me any more). I couldn't see the Teraflex stamp on the housing since it was dirty.
Looks like I'll be ordering a replacement sensor from Teraflex instead as I doubt the Rubicon one will fit....oh well...
