| Hello,
Has anyone put a B body rear end from a 1964 Plymouth into a 1958 Plymouth? Any issues
Thanks |

| Ok thanks really appreciate it. I was concerned about pinion angle as well, and driveshaft compatibility. Look like I need to find a C Body rear |

Location: NorCal | The '65-'67 C-body rear end is a better choice, the pinion angle is correct and the spring perch spacing is close enough for a drop-in...no welding required. |

Location: Springfield, MO | I also understand that certain E-body is acceptable, but the pinion angle is off by 3 degrees. I could not find a C-body for my car, but did find a cheap 71 E-body |

Location: Chestertown, NY ( near Lake George) | Pinion angle is dependent on the height of the front suspension so there are still variables in this issue, slip yoke driveshaft s have a different procedure then the old style shaft. Until the car is at ride hgt., it is impossible to get an accurate measurement on the final pinion angle, if off at this point, wedge shims can correct it.

Location: BELTSVILLE, MARYLAND 20705 | I have used E body rears about 15 times they work great . They bolt right in. You can get a 3 degree shim off ebay and install it when you are installing the rear. With the c body rear you have to re weld and move the spring perches on the housing. With the ebody you can also move your emergency brake cable to the rear wheels ( MUCH SAFER). You can also use your original wheels with this conversion. OVER ALL ITS A NICE AND SAFER IMPROVEMENT. With this e body you now you can use any gear ratio 3rd member and not have to pull the drums with a puller-- just slide off the drums . |

Location: So. Cal | You realize that the only difference between the '65-'69 Cbody and '70-'74 Ebody rears is the pinion angle. That's it - along with maybe different length e-brake cables. All the things you mention are the same. |

Plus, there were more C bodies built and less E bodies. The muscle car builders would prefer the E body stuff so the C body axle would be more common and cheaper. |

| How does a 70 C body rear end work in? |

And the location of the vent hole, not a big issue but it affects the brake hose length.
'70-'74 E-body housing: Vent bolt location: 11.25" from center of housing
'65-'69 C-body housing: Vent bolt location: 7.75" from center of housing |

Location: So. Cal | Thanks for that info Chizler. That provides a convenient way to figure out which axle you really have. Do you have a suggestion for a brake hose to use with the C-body housing? I have always resorted to moving the body mount to get it closer. There is also the '65-'70 A100 van which can be confused between them. Do you know of any differences between that one and the others? |

When I swapped a C-body into my '57 I just measured the required length for the hose to reach the fitting and clear the non-stock exhaust and found a hose with the needed end fittings.
Don't know much about the A-100 other than the width but I imagine the spring pad spacing is different. Don't know where the breather is located.
