Sounds like you have a great kit to build an excellent model. Of course to answer your question, due to the limited production of these kits I do not think any of the aftermarket companies that made parts for plastic scale models did anything for these kits. But another source you might want to try would be the flying scale model guys, I do not know if any of them do 1/8 scale detail parts but that would be a source to look for...
