Although I did find it funny that you mentioned acquiring a factory 4wd underbody, I'm in the process of searching for an importer that can supply me with a rear clip or shell. I think I've pretty much decided that if my project is to continue, I want to do it with all the correct parts. I'm sure it will be more costly that way up front at least, but in the long run it will save me all that fab work and headaches. I'll have the correct floorpan, fuel tank setup, mounting points, suspension, etc etc. And to my understanding the rear suspension will allow me to run crv trailing arms
incidentally, if anyone happens to know of any importers that deal in stuff like this, please lmk. At this point I'd love to see the project continue
