well first of all i ran into a problem right away when i noticed that the diff. bearings were diffrent then the new ones i ordered . the ones on it were a tapered roller bearing yet the new ones are diffrent they are a selaed ball bearing. anyways i huess there was a recall of those bearings so now selaed are used with shims. but my finial drive holes don't line up with my lsd for the b16a tranny?? so know i dont know what to do with an jdm itr final drive fit on a b16a diff. there both 10 bolts but dont line up also i guess the b16a diff. bolts listed in alldata are 10mm yet the ones i took off were 14mm but they thread into the new diff so i can probably re-use them has anyone ever ran into this problem? what finial drive an i use cause i was gonna buy the itr kit with is the countershaft and the finial drive with 15tooth driven 66 tooth final but thats excatly what i have know but i figured the bolt pattern would be diffrent?
