1974 dart, 360, 4L60E, Astrante Dana60 with 354 gear

[Joe Harris]

I would like to install a taller gear but 354 Is the tallest I have foundation for the Dana60. Am considering going to an 8 3/4 Mopar or a Ford 9". What would be a direct swap?

stick with the Dana rear....stronger than 8-3/4....gears are available...here is a link to dr.diff

I'm the only source for a 3.23 Dana 60 gear. This is the tallest ratio available.
