Scratch, (or anybody else knowing 904's)do you know if the front seal on the 904 and the 727 are the same. I have a 904 leak in the front and the local NAPA guy says the front seals are the same. That doesn't seem right, but I bought one to put in this weekend. I have done this many times on the 727 in my race car, but I am not at home and would hate to do this on the week end and have it be the wrong seal. Please advise if you will, thanks!
