Is there any difference between a MAC and TA cover? First things first, I don't need a new rear axle because I never plan on running drag radials or slicks or even drag racing the car.
With that out of the way, I am planning on replacing my diff cover with one that has a fill and drain plug, and would like the added insurance of adding the main cap support bolts.
So my question is, I've searched and see that the two main ones are MAC and TA, is there a difference in the two? The MAC typically sells for $20-$30 less than the TA. Also, is it worth it to get a Main Cap stud kit?
Thanks.

I think the main stud kit is a great idea. I simply believe it will help resist deflection on the main carrier bearing caps. How much? Who the hell knows. It cant hurt though

I have rebuilt several ten bolts, yes they are small and fairly weak. Anything that can keep parts in place is a big plus to me. Lets see what we know about studs: they are used on the most demanding head and main cap applications. Seems like a win/win for the 10 bolt.

Sounds like a plan then. Thanks. I know the 10-bolt isn't meant to handle what these cars throw at them, but I'm on 19" street tires, so I'm going to break traction before I break the 10-bolt.

Has your rear end been freshened up lately?? I really like the tight feel of all new bearings. I have seen ones with fresh bearings take a pretty good beating with no issues. They tend to loosen up quite a bit on the inside after about 50-100k.
