so theres "some" rust, typical of an 80's Mitsubishi
in the windscreen cowel/heater box area in the firewall where every car with this set up rusts out. right in the centre of the firewall, the hoop on the inside is pretty much gone too so will need to make a bigger hole and put one back in.
its not a major at this stage and is pretty centralised at that one point
it was still full of leaves

I also imagine the drains at each side are blocked too because ol mate has bogged up some rust where the inner fender meets the firewall and I get some water coming into the cab from somewhere near there.
theres a bubble on the inside of the drivers door frame, and a streak of rust coming out from behind where the visor is mounted

it also appears that a few unneeded brackets have been chiselled off from the engine bay and some lovely jagged holes left behind
some of the bedliner has failed and is getting rust behind it, so il clean that up

the rest of the thing seems to be ok, I checked out the inside of the doors and they are very nice, needs to have the underside redone, and il be waxoiling the chassis
