which rear should i get?
I'm looking at rears rite now and I'm wondering which would be the best between the 9in and the 12bolt and which company makes a complete bolt in (as pain free as possible) so I can drop the 10 and get rid of it fast. I don't have my own garage but I have a hobby shop on base with lifts and all the tools so I wanna get it done with in a couple hours. I've done a rear before but it was 10 bolt to 10 bolt so I don't have any experience with anything else.

If you are not in a rush get 9 inch from midwest chassis. You can have them ship it assembled. Imo best buy for your dollar. The only downside is they are backed up and its about a three month wait. A Moser 9 will be fast shipping but you have to put it together (I am pretty sure)

Having purchased and installed a Moser 12 bolt, I would probably recommend a Strange rear.

I have a Moser 9". If you retain your stock brakes and emergency brakes, the backing plates will either need to be removed and shipped to the manufacturer, or you can install them yourself and then have the axle bearings pressed on. The axle seals, axles, center section, and vent fitting need to be installed by you. The gears can be setup and preinstalled on the center section by the manufacturer if you choose. Overall, it's a pretty easy installation. Did mine by myself in around 4 hours. Very happy with the unit. Ordered it and recieved it in about a week. I'd also recommend getting the powdercoating, it's well worth the $. If you have any questions, shoot me a PM.

Thanks for the help, I think I'm gonna go with the strange 12. It sounds like everyone's happy with it and its cheaper. I'm a Marine and do not make to much money haha but hopefully if I go to afghan this comin march ill come back with enough $ to get some air under my front tires.

From what I have read the Dana 60 is the way to go.

Some have eperienced gear noise issues, others have had problems with seals and fitment of componants.
I have no complaints about mine, though. Holds up to all the abuse I can throw at it.......

The Dana is the heaviest of the bunch and is less efficient than a 12 bolt.
It whines under light cruise around 1,800 - 2,000 r.p.m. I measured the lash and it is definitely on the loose side. The drain plug on their aluminum cover pulled out all the threads when I went to drain the fluid after the initial break in period.

The S60 is gonna chew up a ton a power but is nearly industrucatable and the cheapest. Theres pros and cons to all of the rears

^^ Correct. The 12 bolt Moser housing does not have through holes for the bolts -- they are blind holes that utilize four (4) shorter bolts instead of two (2) long bolts with nuts. I believe UMI includes a warning in their torque arm installation literature about this setup being able to come loose. My rear came with a set of funky stepped lock washers and I also applied Loc-Tite to the threads. Been over a year now and nothing has loosened up.

I am in the same bind. After the MS3 and stall my rear is on it's way out again. From seeing what my friends have the 9" seemed the way to go but my other friend had a S60 in his Z28 and he admited it was heavier but he said it takes a beating on track days isn't as noisy as his 12 bolt way and is one of the cheaper in price. So I am in no rush since it is a toy and quality and value is top on the list 3 month wait is fine with me.

I have a Moser 9" TrueTrac. Installed it about 2 years ago now. Beat the living snot out of it for those two years with Nitto DR's on the street and a handful of times at the track. Was putting down 330/342 during that time. Now I have 500 to the wheels and I've made about 15 or so WOT pulls. My car dead hooks shifting into 2nd/3rd. No issues so far.
It's as quiet as the 1st day I drove it.
Only issue I've had was when I first installed it I had an axle seal leak on the passenger side. A few axle seals later, patience, and some RTV fixed it. That was 2 years ago. Been dry since.

The Midwest 9 imo is the best your gonna buy. The only downside is the wait but you said thats not a problem. Also you dont have to give them all of the money to begin with. When I placed my order I gave em 1400 and I will give them the rest when its closer to being done.
