I asked in the modified column about putting a NP208J (from my '84 J10 which is getting a Rubicon NV241 OR in it's place) behind an AX-15 (I have the bolt up covered, but was wondering what else I may be missing?) but no-one replied (and only a few even looked). I have a ton of driveshafts to test fit, so I'm pretty much okay there.
