It looks like I need a deep socket for the y-pipe bolts for my 94 y-pipe. Is that what I need to use? Also what size do I need? (I will need to go buy a deep socket because I don't have any but I don't want to get the wrong size and have to keep going back to get diff. sizes)

 

should be 9/16". I have a deep swivel socket for that. if your getin a socket just for it, might as well get the right one. I think you have to have a swivel if I remember correctly. and, if your tool set doesnt already include a 9/16, then you need more tools anways. get a nice set from sears instead of buying that next mod. good luck
