Go to
Kodiak Store and look at their dust caps. If you give them a call, they will tell you which ones you have if you let them know you have a new DRV with the white caps.....
I paid them extra for overnight shipping as I was leaving in two days and wanted to make sure they made it. Very nice people to deal with.
As long as you torque them correctly, you shouldn't have any further problems. Just use a 1/4 or 3/8 torque wrench that can go that low on a torque spec and you should be good to go.
