The late A-body 7 1/4 does not need different shock plates. The axles tubes are still 2 1/2". The 7 1/4 is fine for most automatic equipped slant six street cars, but street/strip cars and manual trans cars driven aggressively can break them. My 318 equipped '77 LeBaron ate one. My 4-speed equipped '66 Dart ate one. The Ford Granada/Mercury Monarch rear end is only about 1/2" wider per side than an A-body rear end and the Ford 8" is stronger and has better parts availability than the 7 1/4. |

The Ford rear ends mentioned are good, but check the axle ratios. Granada/Monarch/Versailles rears often came with tall gearing. My son's car had a 2.47:1 ratio. Also note that some of the Mavericks and Mustangs came with 4-lug wheels. |

73-76 A Body 8.25 LBP rear is a direct bolt-in. Use the shock plates that come with the 8.25 rear
There is also a 7.25" LBP rear from the same model years. Finding the 4.5" bolt pattern does not automatically mean you've found a 8.25".

Interesting question. Would a '66 to '70 B-Body drum fit on the '73 A-Body drum brake spindle? |
