I've my full size D60 and 14blt ff out of a CUCV. Standard 4.56 gears, Trac-Loc in the D60 and Detroit in the rear, changed bearings and seals, brake pads and now, when they are ready to install, I got the above question.

The combo will be completed with a SBC350+TH400+205 already a CJ7 and 39.5x15x15TSL's on 15x10" steel wheels.

Can you helpme complete a list with pro's and con's to narrowing?
  Cons
1. Stability loss
2. Expensive

Pros
1. Fit in more places

Don't narrow them unless you know every thing about axles and still want to do it. Most knowledgable people don't unless there is a compelling engineering reason why (putting a d60 in a susuki sameri for instance, where wms make the jeep look like a road hog).   what is your wms to wms? Wheel mounting surface to wheel mounting surface. Does anyone remember what wide track and narrow track wms measurements are?   often you can stay with stock axles, if you get offset rims. Saving you a chunk of money and ease of getting stock replacement parts rather then paying for a retube and custom axles.   You can even go a little wider in the rear axle then the front. Some of the pickups do this stock. Lots more information on pirate4x4, but read rather than ask unless you like getting flamed as a newbie fawker and told to go read. You can ask in the newbie fawker forums, but these topics have been covered in more detail then you could ever hope for.   You can go with wider then stock axles. Somewhere about 79-81 CJ went to wide track axles which are more stable (preventing rollover) with centered rims. They did this to lower the liability due to rollovers on the street. When swapping in a non CJ complete axle, expect to change the spring perches and shock mounts. You can do this yourself for about $35 for the perches, or about $150-$200 if a shop  does it off the vehicle. They also have perches for armor protection for about $100 more. 
MORE and Currie has these.

Thank you Dan, I think I have about all the technical info on this, what I'm trying to do is to back up my decision to narrow or do not narrow these axles, you know, hear some more opinions.   Keeping the same axles is out of the question. I have already done this before, my '84 (wide track) received D44's out of a Wagoneer, that's about 64" WMS to WMS, nearly 5 or 6" wider than stock.   WMS to WMS in the full size axles is 69.5"   So far I posted the same question on pirate4x4, general 4x4 discussion. http://pirate4x4.com/forum/showthread.php?t=582219   and this is what I've got:   Cons
1. Stability loss
2. Expensive

Pros
