I will be swapping out my diff. cover for one with a new bushing put in and while I was at it I picked up some new drain/fill plugs. I noticed that the head of the new plug looks like it is a 17mm hex and it is a little shorter than the original. Is it okay to use the new one still?

Sorry for the crappy pic.
