Hey Ted, a few months ago I installed one of your upgraded diffs. I was given 2 bottles of posi additive to put in with the gear lube. It's getting close for me to change the fluid. Should I continue to use 2 bottles of the posi additive, or was that just for the break in period? And I'm loving the new gears and the tighter posi. It's an excellent upgrade!

Thanks
Ed
