Does anyone know what would have been a common rear end for a 1983 Dodge 250 Custom Maxivan with a 318-V8? I may be able to get the 360-V8 4bbl from one of these vans, but I was hoping to find out ahead of time what the rear end could possibly be. The van originally had a 318 but was replaced. Jerry |

Only two rear ends available for Vans and trucks...most 80's vans got the 8 1/4" rear, but some heavy duty vans and trucks could be optioned for the 9 1/4" rear... -D.Idiot |

DI, So, the obvious question is, would either one of those from the van bolt up under our '74 Sport? Jerry |

If I find a good truck rear (like 3.55-4.11), I pull the gears. I measured up a truck once and the rear was 7" wider (backing plate to backing plate) than the duster rear I had in my car.... You'd need some mods, some welding, and the correct backspaed rims to make it work...the 12 bolt 9 1/4" is ok for it's application, but not worth bothering with under a slant six car (or even a small block car either)... The easiest one to roll under and slightly modify (non-stock applications), are the early to mid 60's B-body 8 3/4" rear ends.... I've heard Volare/Aspen rears work, but you have to do some modifications as well... good luck on the hunt.... -D.Idiot |

I've seen 8 3/4" in vans before but I am not sure what model it was. |

unless transplanted from an earlier model...the 8 3/4" died in the 1972 model year for passenger cars, and in 1974 in the Truck/Van line.... If you can find an 8 3/4" truck axle, you can have a shop cut it down and order axle shafts to make it fit under anything...they are a very strong rear end...but rear gear sets aren't cheap any more...nor are those rear ends... -D.Idiot |

Tell me about it.. I bought a parts car (duster 340) solely for the rear, anything else that came on it was only a bonus (wasn't much useable left...) Usually those gears are in good condition and you can get away with a $210 rebuild that includes bearings/seal/labor. Thats what a local shop charged me, 110 labor and 100 for the bearing/shim kit. If you find a complete used unit that looks ok chances are you can just run it after you clean it up and change the oil. I have some extra center sections, if anyone is interested. |
