Currie 9" rear end built to place in a GM A Body. 12" Disc brakes, Nodular case, 31 Spline Axles. Rear end was purchase in 2003 and has never been in a car. Still like brand new. $2500 + shipping. Located in the Kansas City Area. Mark
Here are pictures of the rear end. You can see the rear end is still attached to the pallet it came one. The rust is surface rust on the case. Mark
Mark, you're killing me. We just bought a new Currie 9" with 3.50 gears and 31 spline axles, for our '70 Stage 1. The same rearend as yours except we just got drum brakes. I can't believe I missed this original posting! We paid much more, and didn't even get the cool disc brakes like yours. Good luck with the sale.
Do the Wilwoods include parking brakes (4 spd application)? Is it standard width or narrowed slightly for tire clearance? Thanks Dan
It does have a parking brake feature. I believe it would be standard width. I told Currie I wanted s rear end that fit under a 1970 GS. I did not specifically ask them if it was narrowed. I do not believe it has been. Mark
I assume it has some type of limited slip? (Sorry, not very knowledgeable about the 9" internals). Also, is the wheel (stud) bolt circle diameter standard (5 x 4.75"?), and what size/length studs? Will the brakes fit under a 15" Buick rally wheel? Would it be possible for you to measure the axle width (between the wheel mounting surfaces) just to verify that it is (or is not) standard? Thanx.
It does have a limited slip carrier. It is not a spool or a single axle. The studs are 5 x 4.75 for a GM A Body wheel. The brakes will fit under a 15" wheel. I will have the check the width and stud length. Mark
Outside to ouside brake surface 56 1/4". Studs are 1 1/2". I am still looking for the paperwork on the third member specs. I am not having much luck finding it and it has been too long for me to remember. I will continue to look. Mark
Thanks, they have both TrueTrac and Traction Lok styles. Are there any shipping tags remaining which show the weight? Dan
Looked all day and finally found the sheet on the rearend. 3rd member 9" Ford 3.50 ratio T.S.D. (torque Sensative Differential) Limited Slip 9+ nodular street case 9+ Big Bearing overall dimention is 61.25" Pin Offset .94 Axles 2020T 31 spline 5 on 4.75" 7/16 studs Reg Dia 2.78 Dr Axle 28.614 Pas Axle 31.111 It does not have the weight but at the time they sent it freight and it cost $250.00 Mark
Mark can you get apic of the pinion retainer closer? This is an excellent buy for what you get. You stated the overall length is that wheel mount to wheel mount? FYI guys this rear is so easy to remove the gear set and replace I used to race Fords and I could in a half hour change from my street gear (350) to my race gear ( 430) and another half hour back to the street gear. The third member on this rear should handle anything short of 1500 hp and probably more. In al my time with Fords I never broke a 9" and that includes a stint awith a 429 SCJ-C-4 combo in a 68 fastback that launched at 5000 rpms with 12 slicks . I broke everything else but the rear! Oh and there always a ton of third members for sale. ALso the Ford gears are the best for this application as they have a high nickle content and are actually "soft" this absorbs the shock. Some after market gear sets are known tro be more brittle and can break under severe loads. If I could sell my DANA I would be all over this one.
Mark said: "Outside to outside brake surface 56 1/4" I think Mark must have measured between the brake rotors (which is not very helpful). I just went outside and measured the original rear end that came out of my 1970 Skylark. I get a width of 61" (+ or - a hair...it was cold out there) from one brake drum (wheel mounting surface) to the other. This is pretty close to the info Mark found on the rear-end data sheet stating: Overall dimension = 61.25". It sounds like the Currie unit is "standard" width, or darn close to it. Now all I have to do is figure out how to come up with $2500.00 one week after Christmas...... :idea2:
It appears to have the better pinion support us Ford guys called it a Daytona Pinion support. I think somone makes a aluminum one but I like this one
