Yeah mine's a full on resto. It has been stood over 5 years outside before I bought it. Its not bad though, wings and floor pans are the worst. Rear spring hangers need a bit of attention. Engine will get a full rebuild then I need to find an interior cos there was some mice living in it and there wasn't much to rip out when I emptied it.
The intercooler you're describing sounds like a saff 4x4 one. Should be loads out there cos everyone seems to buy RS500 style ones. I know it did when I had mine.
Gonna start on mine again next month and get the shell ready for paint. I don't get much free time cos I'm a wagon driver and am away all week
