I am using AXIS since they did Cummins development work and have all the bits. Their adapters are well refined, my trans is an NGS 370 6 speed
AXIS is working on my jeep for the my engine conversion which is little more complicated then a CJ since I am retaining AC along with a host of other changes
Also Cummins is only15 minutes from their shop
I was unaware Novak had developed an R2.8 engine - trans adapter
The guys at Axis were kind enough to spend time with me on the phone. I would send them my CJ right now without hesitation, if I didn't have a builder lined up.
Sorry to confuse - I don't think Novak has an R2.8 adapter, I just meant they are a source for adapting other driveline components (i.e. AX-15 to Dana 300).
