I bought a LWP low profile cover for my 12 bolt rear. I just worked out a deal to trade it for a 8.5 10 bolt that I wanted all along. The guy didn't want to buy the cover, so I'm looking to trade for a 10 bolt style bearing support cover.
The LPW cover is THE BEST bearing support cover out there, period. This is the low profile design, so you can run a huge sway bar or have extra clearance for an axle tube brace, or whatever.
PN: 201-12.
Details for the LPW cover can be found here:

Right now, I'm just looking to trade for a 10 bolt cover. If I can't find anyone to do that with, I'll sell it.
