Do you have any photos of your table?For all those wondering - I bought the FJ Cruiser locking strut and installed it.
I have a fold down table on my rear hatch and the extra 10* makes a difference when cooking at the back of the truck.
I would say the FJ mod is not worth the cost/result.
Sounds like the FJ strut just isn't quite a right fit, too much modding for the mod. Relocate and fab or mod the brackets and reconfigure mounting to make the strut's length work for a different door? good on you for trying and reporting though. Seems like a good idea, being same chassis, but sounds like configurations are different enough it's not a straight swap.
