If you do a seach down the previous threads we've talked about this many times. But here it is in short.

1. Must have Automatic Transmission tunnel, otherwise there's a lot of work there.
2. Will need to remove Battery bracket to fit smaller battery, or move it to the boot.
3. Will need a different radiator, maybe modifying the front panel.
4. Will need to fabricate firewall mountings for a hydraulic clutch.
5. Modified tailshaft.
6. Depending on gearbox selection, will need to move handbrake lever.
7. The obvious wiring mods.
8. Front intercooler--More front panel mods.
9. At least 3 cartons of beer to relax after a few weeks hard work :)

You'll need a mig welder, angle grinder, plenty of flat metal plate, some creativity and patience. Oh
yeah, and beer.
