I have rebuilt the trac lok in my 7.5 and last spring I installed an 8.8. When I was putting the axels in it looked like there were 2 S springs in the 8.8? I know the 7.5 only had one. Was I seeing things or are there 2 in the 8.8? I hope this is the right place for rear end questions as I didn't see a driveline area. Thanks Bruce
