That sounds good to me: I paid a couple of hundred for a junkyard rear from an unknown year sitting out in the rain and snow for years; put new bearings in the end and discovered the axles had been wallering around and weakened the shafts. The fluid is nasty as hell. Who knows what I havr got and now I'm in almost $500. Yeah, pay the money.

I am interested in the same set-up. I have an 8" third member from Currie and it was very good quality and has worked well so far. That is a good price for what you get. You will be happy with it until........the credit card bill arrives in the mail.
Sorry, I assumed that the rear was used. However, unless you are making in excess of 400rwhp, that rear is a waste of moula.
You can buy complete 9" assemblies from the boneyard for under $150 if you look hard enough. Buy the LSD and gears for around $500. You don't need 31s unless you are hitting low 10s. And rear disc conversions are also cheap and plentiful.
I was in the same place as you are, buying a bolt-in unit from Currie seemed attractive until I ran the math. It all depends on how much effort you want to put into this, if all you wanna do is make a phone call and whip out the credit card then the complete units are nice, but with some effort I got a 9" with ARB softlocker 31s and 3.89 gears for much less than half that amount.

at the flywheel I am making 500 HP and 497 ft. lbs of torque. Due to the tranny and other stuff I am lossing about 40 HP by the time it gets to the rear. So I estimate in the end I will have about 450 HP to the rear maybe more after a dyno tune. But even more importantly is that ~4600 ft. lbs. of torque will be hitting the rearend. I have been doing the math and have come to these conclusions. I could get a rearend from a yard for about 100 but most likely the whole 3rd member and axles will have to be replaced as well as it will not come with the pinion support or disc brakes. When you add up all the parts it comes out to almost the same as the currie unit plus I would have to build it myself or have someone else build it for an additional cost. I think I will just end up buying it complete from currie. Atleast I will also have the satisfaction of knowing it will never break and it is being put together by professionals.
I paid zero dollars for a 57-59 Ford 9 inch rear, with a WAR case center section, and Detroit Locker with 3.70 gears and 28 spline axles. If I was you I'd skip the pinion support and the Nodular case. Even a std 9inch housing will handle what you've got. unless you're planning on stuffing it under a strip car with big slicks. For the street, you don't need all the bells and whistles.

How do you like the Detroit Locker? I was thinking of going with that. I have a 9" rear with an open rear right now. How is the DL on the street? The motor I'm putting in my Mach puts out 490HP at the crank.
