Location: Central New York | Hi all, I'm taking the advice of all the members that were nice enough to reply and procured a suitable rear end for Belva in preparation of the swap.
My question: What is proper (safe) way to remove the old one. I'm sure most of you have done this and I would like to know the right procedure so I don't end up with a few hundred pounds on my head. Thanks again. P. |

Location: Perth Australia | The whole rear?
Unbolt the rear spring hangers on both sides, undo the drive shaft, shockers, brake line, then u bolts holding the rear to the springs then roll it out on its wheels
Pretty simple job, but without knowing your mechanical abilities, I will give you a caution, lots of jacking (unless you own a hoist), lots of heavy stuff that will at best, hurt you if you treat it wrong, so be carefull.
Think of the senario of someone doing this job and doing it carefully, jacking the car up (nice and high), supporting it on stands, going through the steps until the second last one (undoing the U bolts) and having the car fall down...
Had the stands suporting the rear of the car on the axle, not on the chassis or body of the car.
This could happen in all the excitement of doing the job

Location: Central New York | Just the rear end, the springs are ok and staying. The car is sitting on 4 H.D. jack stands at the corners on the FRAME.(ahead of the rear tires and behind the fronts.) and the suspension is hanging.
I understand there's jacking involved. I guess that's what I need to know. When do I jack up the rear, in what order should I undo the hardware..... stuff like that.
I'm pretty mechanical, I just don't want to hurt the car. (or me) |

Location: SD | I would suggest putting another pair of stands under the rear end. That way, you can unbolt everything and have the weight of the rear end resting on the stands, and not worry about it dropping. When everything is finally unbolted, use a floor jack to let down one side at a time. At that point, like Mick said, you can roll the whole thing out on the wheels. |

The '56 has 41" spring centers so there is no drop-in 8 3/4". My '56 Plaza has a '65-'67 B-body 8 3/4" with the 44" spring perches moved inboard....overall width is perfect. |

| Just about any other rear end you install will need the original spring perches to be cut off and welded to the new rear end. The 56 Plymouth uses splayed rear sprngs which means the leaf spring fronts are closer together than the shackles at the rear. This moves the perch points inboard away from the backing plate. The perches are also the lower mounts for the rear shocks. In all other aspects, ttotired and 57chizler together "nailed the response for a 1956 Plymouth rear".

That's the way my '56 is done but I don't see why the later u-bolt plates with the built-in shock stud couldn't also be used...would probably require shock of different dimensions.
