help identify RE trackbar

I recently picked up a second hand RE adjustable trackbar but am unsure its the correct model for me. I have a 99 XJ with 4.5-5 inches of lift

This is the description the seller gave me-

I have a used rubicon express chromoly front track bar for a TJ. Its in good shape has less then 5k on it. It should fit from 3.5 to 4.5 inch lift. I'm running a 5 inch lift and it works fine.

I purchased it as I thought it was a RE1600, but it appears to have the super flex instead of a tie rod end. So I assume its either a RE1610 or RE 1660, How can I tell which one its is and will the 1610 work on my XJ (If I buy the 1665 bracket)?

yes it will work with the frame bracket.

you can tell if it is the older or newer model by if it has an "inward" bend. RE did this to clear all trac bars for a d44 front diff. the older ones are straight from bolt hole to bolt hole.

looks like I think its the RE1610 which means its too damn long for the XJ
