Is that the factory 3:07 gearing in the pumpkin? Did you rebuild the LSD or just going to run it as is? It has a factory TrackLok LSD right? I assume that is a clutch pack style LSD? |
The centerline is very close. I needed shorter axles because the Viper diff is wider overall.
The rear is the 3.07/3.08. I haven't rebuilt the unit. It looked and smelled brand new when I took the rear cover off. I bought this pumpkin years back from a Dodge guy on eGay. He said a tree jumped out in front of a very low mileage Viper causing a total loss. I don't know what style clutch it has, but I figure the Viper was a much heavier car and if the Dana 44 was good enough for it, it will be fine in the little Mazda. I think the Viper was a '99 model. I read somewhere the rear is actually called a Dana 44.5, whatever that means.
Good news is, I had installed a Dana 36 in the 2nd gen RX-7 and never had a problem with it once I had it rebuilt. The 44 is a lot beefier.
