Was it this year that ran an exposed tail shaft on the commercials? And how strong are these units? We have decided to run a mild 289W thats sitting under the bench instead of the flathead for the old mans modified. He wants an old style diff out back. I am aware of the halibrand style covers available for more common diffs, and are considering going down that path.

Jimbob, are we talking about a heavy duty truck type diff or the open drive shaft variety on the Ford utes of this era? If it is the latter,then my recollection is that they would have the same strength as the sedans etc with a lower ratio,best to steer clear if you are pumping extra "horses" through it, for long term reliability............Frank.

Wasn't sure about what year or style they were from, just knew there was no enclosed tailshaft. Have talked him into a borg warner or 9 inch with a dummy quickchange hat. He really just wanted a transverse spring.

Cheers and beers

Jimbob,the late diffs can be bracketed up for the transverse rear springing,no probs.In the long run the work will be worth it,unless you have plenty of spares,and time, to keep repairing the old diff.Earlier in the rodding world,Y blocks were adapted to late 30,s-40,s rods using the original box and diff,with the constant requirement for replacement cogs and axles etc..............Frank.

He's got an old 34 diff laying around so I'll just chop the brackets off that, and use the 34 spring.

Cheers and beers
