Porsche's evolution-not-revolution approach to the original 911 is both a blessing and a curse. And we're not talking about the driving experience. Instead, replacement panels are the subject du jour, or at least of this page. The upside of that slow evolution is that panels for aircooled 911s across the years are often interchangeable. The downside? Getting exactly the right panel in cosmetic terms isn't always easy. Until classic Porsche parts specialist Dansk came along, that is, and started making repro' parts for nearly everything. Like this new rear engine compartment crossbeam. It's compatible with a wide range of old 911s, but the specific shape of the rear outer skin is particular to the G Series models. What's more, Dansk is also preparing a similar panel with F Series cosmetics, so they've got you covered either way. Pricing is around £420, the part number is 1680601400 and you can find out more from www.jpgroupclassic.com.
