I tried to install the ring gear on the open cattier I have and I bottomed out the bolts and still had about 3-16'-1/4" gap between the ring gear and carrier. I did not have lock wwashers installed on the bolts. The bolts were from Randy's R&P specifically for installing 5:13 gears on a standard 4.56 and lower(numerically higher) carrier(I only got the bolts and didn't notice the lockwashers on my 3.73 setup until the bottoming out of the bolts occured). Do I have the right carrier or are the lockwashers mandatory and the cause of my problem? Pic one is the 3.73 carrier, pic 2 is the 4.56 and lower carrier with measurements, and pic three is the 3.73 carrier again with measurments.
