You should build a new exterior from scratch. I am already making an R160 exterior to wrap around JayJay85's interior.
There are too many people throwing around the word "my", and there are way too many versions of the R160 being worked on right now. In the past month, i've seen at least seven R160's being made, all not crediting JayJay85 for his interior work, and some not crediting Error46146 properly. I don't mean to sound like an ass, but please, and this is meant for all ears: the content made on BVEStation wasn't made for you to keep editing on it, it was made so that you get a feel for object building. You don't have to keep editing something; it creates a mess out of the coding and the release is an eyesore.
Please, start making your own objects from scratch. You may think its easier, but you don't learn a single thing from editing, without asking me, or a ton of other developers a truckload of questions.
