DIY rear coil spring mount reinforcing. Who has done their own?

[TimE]

This is the Boss bracing kit. No welding..
...

That is what I have put in my GU IV Wagon, no stuffing about, fits right in there.

Job was done in less than an hour (with access to a hoist) and hopefully will now not have to worry too much about towing 1.6 ton camper and other "necessary" camping items (eg beer!)
