Rusty Jimny, rear body mounts / chassis gone

Hi folks, new on here and looking for some inspiration.
Recently bought a jimny (99, 90k) for a bit of fun needing "some" welding in the boot...


For now its project name is the rust bucket.

After removing rear trims and poking around with the grinder...


Boot floor/rear arch junctions are gone down both sides and along the front.


Outer rear arches/back panel are falling apart.


Rear body mounts are no longer attached to the body!
One of the rear chassis to body mounts has rusted through.



Can handle the patching ok but the mounts have me stumped.

Only plan i have at the min is to raise the body and construct some arrangment bracing off the seatbelt cross member and the rear pillars either side of boot door as i wouldnt think any existing metal in the boot area would take the load.

Anyone had to re-attach the rear mounts and like to share their ideas?

Unforunately a truck/tray back end is not an option as id prefer to keep the std body shape.


Cheers Neil

I am following this with interest. Those outriggers are truly a worry.

I saw one guy who replaced all the sill etc. with thick rectangular section tube.

I have a better idea - it was something I wanted to do to my SJ but after 22years it was way too good to warrant it.......get a Blitz kit for it. I'd love to do it. :woohoo:

Do you want to repair it to roadworthy standard or for just offroading?

Hoping to get it back on the road. MOT is booked for next Thursday lol.

Got the chassis holes filled with 1.4mm steel then going to reinforce with 3mm plate and angle.
Subframe for the body mounts is almost done, (50x3 box) and ready for trial fit. If anything it should be more robust than it was.

Any thing I should look out for?
I like the idea of a tray back but I want to keep it practical for non off road stuff lol.

Will update with some pics again

The way these things rust is unreal! I was poking about in my boot recently as well and found a few holes too. Are you doing the welding yourself?
