Default what rear ends will fit?

i think the rear end in my car must have been swapped before because i have 2.43 (if i remember right) in there now and its an m6. new gears are around $200 and ive seen whole rear ends for sale for $150. there is even a ford 9" for sale for $50!

i dont really want to try to swap gears because ive never done anything like that and i dont want to destroy them by not doing it right. swapping in a rear end with shorter gears already in it seems much easier.

will a rear out of a 94 bolt right on to my 2000? will a rear end out of any other car fit? the 9" i found was out of a '80 f-150 and ive seen a few 94's being parted out

anyone know what gears are in the 94s? would it be worth the swap?

you might mean 342 i know my m6 came with them...the 9" would be the best swap beside a 12 bolt if you wanna make real power. With the ford 9" you would need a good fabricator...but its worth it... camaro 10= no no

my gears arnt stock. thats why i want to swap it. it must be a rear end from an auto. i think they have the 2.43s, i could be wrong but i know its not the same as the m6. its way too lazy off the line.

the speedo was way off when i bought the car so i used my diablosport to calibrate it. changed the rear end ratio till the speedo was dead on.

ive posted my old speedo problem a houndred times, sry to everyone that is tired of hearing about it

Dont know of any 2.43 gears... Maybe 2.73s from an auto. You said you had the speedo problem fixed with the diablo so ill leave it at that.

The 94 rear will fit in your car. If the car was a stick 3.42s, auto 2.73s or 3.23s. Its probably a 3 channel (no tcs) but will bolt right up. You will need your ls1 brake brackets unless you want to use the lt1 brakes.

yes! 2.73. idk why i always say 2.43. thanks for the help.

BStowers023- i saw the 9" on criegslist. in the quad city area. it just said "ford 9" $50". it was a short description. just said it came out of a 1980 f-150.

On that 9" you would have to have torque arm mounts fabbed and welded, axle tubes shortened, brakes mooded to fit, axles shortened, etc..... not worth it....

yeah look for a moser 9" or a moser 12 bolt, new they are both over $2K and used you can find them between $1K and $1.5K usually. But if i was you i would run your stock 10 bolt until it breaks, some of them are stronger than others and will last a while, my buddy with a 98 Z28 H/C/I nitrous car ran his stock 10 bolt over 50K miles before it broke and thats taking it to the track once every month or so

i wish i could go buy a moser 9" but i just dont have the cash for that. i was going to get a used rear from an m6. would going from 2.73 to 3.42 be worth the swap? i dont want to waist the time and money if i wont even notice

I know going from 2.73 to 3.42 with my stalled auto made a big difference in throttle response and around town driving. I'm sure it would do the same for an M6. 2.73 probably sucks pretty bad with the 6 speed. I would do it if you can find a cheap 10 bolt already set up.
