Mag-Hytec front diff cover

[TRAMPLINEMAN]

I just received a front diff. cover for my '06 and have a question. When did they stop using an o-ring on the diff. covers? My '97 had an 0-ring in the front cover but this one for my '06 has a gasket.

The rear does still use a O-ring. There must have been problems in the front so, they switches to a gasket.
