Anyone use Energy Suspension Frame Mount Bushings on there F250 4x4?

[Madman]

I've seen on and off talk that using the Energy Suspension frame mount Bushings for a dent side will work in a bump F100 4x4 (not on this forum), but wanted to see if anyone here has tried to use these, especially on a F250 4x4. I trust folks much more here than anywhere else!

Here is what I'm eyeballing:

I did read on here that the ones from Prothane that state they are for 1970 F250 4x4's didn't fit (Prothane 6105)

Anyone have luck using those?

I have the spring and shackle bushings and the frame mounts on my truck. It's a 79 chassis but they've been on there for close to 10 years and haven't had an issue with any of them.
