Default 63-64 Diff's and judging

So, checking the 6th edition Judging Guide, it states " The following information is not judged but is provided for reference only" when it comes to the casting # for the diff case. Understanding the rarity (and unreliability) of these units, am I correct in assuming I would not take a deduction for having say, a '70 case in a '63? Trying to gain an understanding before I spend a lot of time and money locating and building one. Thanks!

From what I understand, the judges don't touch the car, don't put it on a lift, and only judge what they can see.
So parts like the trans and diff don't get judged.
Others can correct me on that.

Partially true. If a judge looks under an early 63 and see a Muncie transmission or looks at a late 63 or 64 with a T10, there should be a deduction. They will also look for tags, etc. You are correct the stampings are not looked at. When I judge 53 - 57, my partner weights 155 pounds. He dons a painters suit, slides under the car and looks at everything, nice to be trim at 75.

My 63 had a 76 rear when I got the car. It took some time but I found the correct parts with the correct castings and stamps. Think I paid $400.00 for the correct parts.

Thanks. Beautiful Silver Blue SWC, BTW. That's exactly what I'm working on. I agree, though my concern is the casting number can be viewed, if you're ambitious. My understanding is it's typical to do things like drop the spare and pull the air cleaner, but nothing involving taking things apart...

Yes, the judges will ask you to pull the spare so they can look at the rim and tire as well as the inside of the tub. They will also ask to remove the air cleaner and the shielding over the distributor. You do not have to do any of this, but you will take a deduction on what they can not see. This is different than being able to see a part but not being able to read it. In the case the advantage goes to the owner.

Even in the pristine, temp controlled spaces of an aircraft hangar the judges will only go so far....I doubt your numbers on the differential will get you in trouble.. But then again



My regional 93% Second Flight car received a lot of scrutiny,

I hear you Frankie. It can be especially tough when you find out things like your bumpers or jambs are "too nice".

I did get hit with that deduction,

However my jambs and underhood lip and other such things were "dulled down" when the car was repainted in 2018 with single stage.

I hate the too nice deduction! Especially for finishing like chrome and paint....I do understand the production line pushed out a lot of “nominal” grade finishes...but the border line here is so grey!

I had my original horns blasted and repainted and got half deduction at the regionals because they were. “Too nice”! 🤷‍♂️

The '63 I'm talking about was shot in lacquer, and the jambs were "as shot". I guess my atomization was too good. :-(
