So our front diffs use an R180. Looks like the R180 was used in other trucks liek 4 banger 1st gen frontiers (r180A) and the 720 (r180). Will a gear set from one of those work in ours?? Not that i am going to do it. Jsut wondering. https://www.4x4parts.com/catalog/advanced_search_result.php?keywords=r180
