Alright need some advice here please.. i had ordered the wrong diff for my 1500 Silverado non HD which i ended up ordering instead one for an HD.but the gear ratio is the same for the front of my truck and it's 4x4 will i be able to use is still or do i need to get one for a non hd.. i heard from a friend it would work but would like an second opinion and will i run into any problems in the future if it turns out i may use it?? I do know the housing is a slite bigger.. so that being said what should I do..
