Can anyone tell me how the Mopar 8.25" unit stacks up against the drop-out 8.75" in terms of efficencty and weight? I know that a lot of small-bloch Dodge anbd Plymouth racers have replaced the 8.75" rears with these lighter Chrysler Spicer types in the past, but I am wondering about total weight, aftermarket axle availability and strength.

This would be for my 2,700-pound, turbocharged slant-six powered, 904 equipped, bracket car.

Any information would be much appreciated. Thanks in advance...
