9 bolt borg-warner rearend fit in a 2000 Z-28 I have heard the 9 bolts are stronger than stock 10 bolts. my car has 2.73, and am looking to change them. I came across locally a complete 9 bolt axles discs and 3.45? for 200$. I am wondering If they are interchangable and would it be worth it for only $200 plus labor to install? Please be honest just looking to get a better gear though this might be a very cheap way out.

i had a 9 bolt and couldnt give it away. if its an iron caliper rear, then it takes a special fitting for the brake lines too.
they are actually 7 7/8" and have 30 spline axles. stock for stock they are stronger, but its kinda a waste, IMO.
for 200 you can almost do a gear swap if you did it yourself.
local price here is 120-150 labor. nother buck or two and you can have a gear in yours.

9 bolt pro's:
-Slightly stronger than a ten bolt.
-Can shim the cones to make it "tighter"
-There are some upgrades to make it stronger.
-Bolt in axles instead of c-clips.
Con's:
-1.5" narrower per side (you'll have to use custom wheels or bolt on spacers)
-No ABS provisions (you may be able to modify one to use 4 channel ABS..haven't looked into it).
-Didn't offer our style of rear brakes. You'll either have to fab to make your ls1 brakes work or if you get an 88-90 model one that has the Alum. PBR brakes you can use them (they're the same as 93-97 LT1 F-body brakes)
-Parts are slightly more expensive and can be hard to find (if you don't know where to get them); you can find whatever you need for one on www.thirdgen.org if you're willing to search. I have a huge post on there...just search under drain89 and 9bolt
I said f-it and bought a strange 12 bolt.
You could sell it for more than 200 on thirdgen.org...especially if it has the later style rear discs on it.
