The only correction I have found is produced by MDC, located in the UK. They ship free outside of the EC, but I don't know how long they take. They have a resin wheelwell set, cockpit set, & external set, and a reduced price for all 3. They look really good, I plan on getting the complete set (about $). They are listed near the bottom of the page, with pics. Hope this helps !
