2012 Jayco jay flight swift 154BH Axle Size for Over / Under?

[NATUREBASEDRV]

Hey, looking to see if anyone knows what axle size the 2012 jay flight swift slx 154BH has for the Dexter over under conversion? It's either 2 3/8" or 3"...

Jayco has no clue and told me to call Dexter, who makes the axl, and they want to serial number. I won't have access to the axl for another week (in storage) and want to purchase the conversion kit right now.

HELP!

It is likely the same size as all the swift slx models...

Anyone here do the dexter kit? Which size did you purchase? 2 3/8" or 3"
