8 3/4 axle upgrade to LBP

Tracy, The axles are 28" long from the wheel face of the flange to the end of the splines. Now the axle only goes into the housing till the snap ring hits. The retainer uses the snap ring to hold the axle in place. Am I Right or Wrong on that? So from the snap ring to the spline end it is 25 1/2". From the thrust block to the housing end where the snap ring seats it measures 26". I have an extra 1/2" clearance from the end of the axle to the thrust block. I hope this clears it up.
