It's been awhile since I last posted anything but I've been busy with the birth of my second girl. Now she's 3 months old and my oldest is now seven. I'm also a firefighter at to different departments and going to school part-time. But during my off time occasionally I get the chance to tinker on on the Comanche. Here recently I've been working on trying to get my Ford 9 inch in. I'm at the point of setting my pinion angle and butting everything back up. My next big project will be replacing the Aw4 auto with a manual. Not sure right now if I wanna go nv3550 or ax-15. I've heard that the nv3550 is stronger but the ax-15 is more reliable. The nv3550 is also picky on its fluids. I do know if I go with the ax-15 then I'll need the 94 and up due to the external slave cylinder. And I also know that the nv3550 has a better crawl ratio in first at 4.01 compared to the ax-15's 3.83. What do you guys think? Nv3550 or ax-15 tranny and why? New or junkyard or rebuilt? My other question or concern is after the tranny I wanna go low low with my gearing. I've got decent low gearing in my diff with Dana 44 and the 9 inch having 5.13's. I was thinking of doing a doubler setup with the northwestfab doubler kit since I have a spare 231 setting around (price is around 700$ for kit or 1600$ for a built one. Was also thinking of running a doubler with a rubicon case that I can pick up for $1100. Also if not the rubicon case I'd like to run the Tera low kit if I were to keep the 231 (price on the Tera low is around $700). Here's another idea...I've got a ford np205. Is that overkill? Attach that to the doubler and run that? What do y'all think? Would the np205 mate up to the doubler kit by nwf? Any ideas? Let me know what y'all think. If you guys have any suggestions that would be helpful please feel free to post your comments. Thanks
