ok i have a 94 firebird 3.23's non posi.... i will be putting in a 95 z28 3.42 posi rear end with disc brakes and TC... what extra stuff do i need to do and what are the steps to taking the axle out and putting the whole new rear end in??

 

I believe its just a longer brake cable since you are going to disk brakes.

 

With the exception of needing a longer e-brake cable, it should just bolt in.

However, when I had my V6, I wanted to do the same thing but for some reason people told me not to buy a rear-end that had traction control. Which may cause some problems because it requires a computer to work, and the traction control cars my have a different ABS setup. Check with the LT1 guys.

 

you will need a new master cyclinder if your going from drums to discs i do believe. just get a 100$ SLP posi and make yours posi.

 

well the reason i am doing this is .. its a great deal..... im only paying 200 for eveything.... and i jsut dont want posi i want some higher gears too..... the car this is coming outta only has like 50,xxxx on it.....

 

are you going to keep the brakes, i thought jeremy was going to buy them,

if you do get the brakes , you will need a new proportioning valve in addition to the rear brake lines , and e-brake cable

 

im not really sure yet..... it will be some time before he gets all the stuff outta the car...

thanks

 

I did this swap...

First off... you do not need a new master cylinder or brake proportioning valve... I have had mine with niether for over a year, and they stop much quicker then then my drum brakes ever did. I have autocrossed and road raced on them.

As for e-brake cable you jsut need the left and right one off a z28 or a 4-wheel disc brake v6 from 93-97, which is pretty rare I think y87 only.

I did it in a parking garage with 4 jackstands... a hydraulic jack and the stock spare tire jack.

Get a big breaker bar for the bolts.... I didn't have one.... made things difficult but I posisotn the wrench above a jack so I could "jack " some bolts loose to be taken off.

I suggest taking off the entire rear axle along with the torqu arm and drive shaft connected. Its really really hard to get the stock 2 piece driveshaft off the torque arm wqhen it is all on the car but once off the car takes less ten a minute to do.

Along with taking hte old driveshaft out i woudl defiently upgrade.... go for ls1 if you can afford it unless you are like me and canot I got a used Lt1 Driveshaft for $25.

when you rebleed the brakes.... use a clear bottle and a lawnmower fuel line(any car store has them, its a clear tube0 and bleed the brakes till you see the air gone.... keep doing it over and over till when you dirve the brake feel solid. I know a couple peopel have had problems and rebled their systesm like 3-4 times it took me 5 times to get it right.

I can get mopre specific if you wnat or can answer any questions you have.

my AIm is in the sig....

 

thanks for the info..... so ill just to bleed the brakes and get some new brake line then..... and the e-brake thingy..... and what about the TC system????
