Hi Greg,
Wow the clutch body on that would've been absolutely SHOT ! as that's what has done all the damage.
It never ceases to amaze me how some people will let a machine get that bad as it would've been vibrating it's head off to get like this.
This one would qualify to have the Jones Gusset repair method applied to keep the broken rails straight while all the the rest of the fractures are zapped up to neaten it up as if nothing was ever done to it. The other option is to send the chassis over to WA and get Shane to replace the full rails with newly manufactured ones.
Cheers,
BB.
