Dodge 575 Diff

G'Day just joined up the forum been looking thru all the photos...alot of good stuff on here!

I've got a question about a my Dodge 575. Are there any Diffs that are a bolt in replacement (using the original 5 stud wheels) that have a more Hwy friendly ratio? Did any of the AB inters have a 2 speed diff with the 5 stud wheels?

Mick, I think this question has been asked & answered previously and i think the answer is that your Dodgey has a Dana diff which is the same as what lotsa Fords used including the famous 9 inch.... so in short, if it is a dana, any of the quicker ones will bolt straight in..

Thanks Sarge, I did a bit more scraping and finally found the diff tag...wasn't where I expected it to be!

Its a Rockwell Diff D100-NX-14 with a 6.2 Ratio. I know absolutly nothing about Rockwell Diffs (this is my first truck) Is it easy to find other centres that will bolt in, I've built plenty of diffs before but never had a go at one of these
