Novak vs. Advance Adapters

OK, so I'm doing the 4.0 swap, and I am dropping in an AX-15 tranny, which I will be adapting to my Dana 300. The problem is that I can't decide which adapter to use. The novak adapter is cheaper at $118, but the AA adapter comes with an index retainer and is $173. Do I need the extra part? If anybody has any info, it would be helpful. Thanks.

I was very happy with the novak adapter. The "index retainer" looks like a new input bearing retainer for the t-case. I'm not sure what it does, or why you would use it.

the index retainer alows you to roll the case down for better driveline angles with out lowering the whole thing. depends on how much lift you will have and if you want it or not.
