Hi Jeepking59,
Sorry it's taken so long for me to see the message. I did go with a 1350 for the rear driveshaft. Mine took 6 weeks for MoTech to complete. I pestered them often and they knew it was my only vehicle and Daily Driver. I ended up putting a Redrock Hood on so I could fit the engine cover. I have a pic, but again, not sure how to attach to message.
