Nice spreadsheet, Tim! Although having it in 3 places seems like a nightmare to maintain.
Tom, you are running a 22R, right? If so, there's gonna be some redundancy we can take advantage of (same water pump, radiator, oil pump, etc.). I'm still assuming that I will be the only mini IFS at this point, although you never know. There will obviously be IFS trucks, but they'll be FJ Cruisers and Tacomas I'd guess. What moron thinks he can drive the Rubicon in an old mini truck without an SAS, anyway?
