Well let me help you unless you remove the whole rear end you will be down there on the ground measuring and checking, the 9 inch and 8/3/4, you can set them up with the center clamped in a vise so it looks like your letter is very self serving. Like it's been told to many with the older cars, if you want the new stuff than get a new car!!

Shows how well you think things out before trying to stir things up!
I don't see where the request to allow aluminum 9" and 8 3/4" center sections have anything to do with the new cars or the extra labor involved with gear changes in a Dana 60 or 12 bolt. It's for racers who
already have the 9" or 8 3/4" in their cars and would like a replacement option for them that is stronger, safer, can provide contingency opportunities and makes the factory happy because they can sell more parts! NHRA, in typical fashion, confuses the situation by not being specific and allows at least Mopar to post contingency for them. Of all the things that NHRA has allowed with aftermarket parts, like blocks, heads, etc., an aluminum carrier would likely have the least amount of performance benefit.
I'm curious if Mopar posted with NHRA for their aluminum 8 3/4 center sections in Stock in years before the Drag Pak Challengers were introduced. If so, then it would imply that they would be legal in older cars! Any Ford or aftermarket postings in years before the Mustangs came out in Stock?
