They are not worth 2k to a road runner guy.... 8 3/4 axles were the standard axle for the B & E bodies and are a dime a dozen....
People watch too much custom car reality show. Like the one show they paid over 3000 for a grille for a 73 challenger... or so they claimed
Same here people don't like them like being caught on a moped or in a Kia!

Well that is what in was thinking but just goes to show the mentality of the GM guy trying to get rich in anything with a pentastar
I doubt it. I broke 3 of those in 4 years behind a 318 with a 4 bbl, dual exhaust, 340 cam, Holley 600 in a daily driver....
A 318 built to 340 specs will break those with daily driving eventually, even if you don't beat on it...
The only thing I might do to mine is stronger axels from dr diff. If I break one! I do have a few spares though.......
What I find funny is the people who swear the 741 case is too weak to run....it's actually stronger than a Ford 9 inch

Hey bartender!
So if I'm reading this correctly, a 7.25 for a 73 Swinger is narrower than a 7.25 from a 69 Barracuda?
I would go with "or so they claimed"....
I still wonder how the hell Meme's 7 1/4 held up in Victoria with those times he used to pull. Prob the gears. 2.45 I think he ran.

They should be the same but it will look narrower in the barracuda because the barracuda 1/4 panels flair out like a duster body giving more tire room
Looks like it. You have to watch the housings one has a offset pinion for 2.45 and higher the other is centered for 2.56 and lower. We beat the heck out of this in that thread with pics. You can get the 8.25 2.45 trackloks cheap but will not fit into the carrier with the centered pinion. The desireable ones.
Hey whats up today gang?
Car show at the O'hare Hooters today...
I'm not sure if I'm going yet. My uncle was supposed to get back from AZ last night. It would be cool to get his Roadrunner there and get Eddie and his brother to bring their Roadrunner and Dart so there will be at least 3 Mopars there....

So what's your opinion on the pinion???

I didn't measure when i did the swap (to get bbp). The swinger axle in the cuda set the rears inboard quite a bit compared to how it was stock. Tires actually rub the wheelwells when really articulated. I chocked it up to differences in the wheel backspacing (which i didnt measure either). Interesting stuff. May have to get out the tape measure..
But wait folks there is more, The carriers are different also. the one on the left is from a 3.23 rear and the one on the right is a 2.45 carrier. You can see the high ratio carrier flange for the ring is shifted back by almost half an inch so they are only able to fit into the respective carrier.

Hey bartender!
I need to see what's in the Dart Sport. Was a 340 car. Maybe it's got a 355 gear in it...
I am all schooled up on them now for sure and so is Memi!
It is just a break with the high/low gears. The carriers are the same length say for a 73 2.45 and a 3.55
Karl, u up in Chicago area?
