original rear end '68 Charger

[Silver Charger]

Anyone know what the stock rear end is for a '68 Charger R/T with a 440 ?

[TylerCharger69]

that would be a 742 case......it can vary on the ratio though...I'm going to guess the most common were 3:23   and 3:55 sure grips  there may be others, but that would be the most popular.  Is the differential tag not on yours??

[8WHEELER]

The 68 R/T Charger with an 8 3/4 rear would have  ''as said above'' 742 case, 95% chance to have 323
gears with an auto car, because most every 4sp car would have a Dana. Anyway I have never seen a
68 auto car with 355's the only other gears I have seen in an auto car was 391's and that is rare as hell 

So like the saying goes anything is possible, but not likely, so 323's maybe or maybe not a suregrip was stock....

    I didn't mention the 3:91...that would be rare....yes....I just ASSUMED it was a sure grip,  or an R/T car

[TylerCharger69]

Oops...scuze me..."in"  an R/T car....not   "or" an R/T car...lol....geeeeeeeeees    I'm going to bed....

In 69, to my knowledge, 3.91's were not offered in any Charger....not sure about 68's though

The base rear for an auto car was a non Sure-Grip 3.23 ratio 8¾ rear.....
The Sure-Grip was optional.
The optional 8¾ rear was the Sure-Grip equipped 3.55 ratio with auto trans
The next step up would be the Super Perf Axle package 4.10 Dana rear for an auto

4-speed cars came standard with a 3.54 Dana or optional 4.10 Dana

I've yet to see a '69 with the A31

[694spdRT]

So the A31 High Performance package with 3.91's was not available in the Charger...learned something new today.

[TylerCharger69]

yeah...I new 3:23  was most popular in that case....I figure 3:55  was a rare option....but I knew 3:91  wasn't available too.  Open or Sure grip....I'm not sure about that though, but I'm sure there are those here who do know

Not in 69 at least.   I think that was a RR /Super Bee package

Thanks for the info Chris. If non RT's were not available with any gear above 3.55 in the 8 3/4" rear could a 4.10 Dana be optioned out on a non R/T car?

[8WHEELER]

A friend of mine has had his JJ1 Gold 68 R/T since 1977, he bought it from the original owner. He told me
in 1980 she ordered the car with pass side headrest delete ''she was 5' tall'' and 391's, I told him at the time oh right sure!!
But over the years I found this to be true, you could order most anything, but it was ordered.

Not to my knowledge.  the A32 Super Performance Package was only available with 426/440 autos as well as the A34 Super Track Pack with the 4-speed

[hemigeno]

Based on the Dealer Data book, the A31 High Performance Package (3.91 suregrip) was available on Chargers.  Chris, that's even spelled out in the Confidential Price Bulletin I gave you a copy of...     MSRP of $102.15

However, the 3.91 ratio wasn't available in an R/T (440 or 426 cars).  Only the 383 4bbl cars (auto or 4-speed) were offered that axle ratio, as they couldn't get the 4.10 Dana.

I didn't even realize that was the case until I read this thread, as I thought that axle was offered on 440/426 auto cars.  Learned something too!

Supposedly nothing above 3.91 on a non-R/T - but that doesn't cover the Bronze '69 non-R/T prototype that had a Hemi automatic in it...

I figured the 3.91 was not available in the R/T due to the availability of the 4.10 Dana. It was the 383 4 speed cars that got me thinking because of the apparent lack of available gears. My brother-in-laws Hemi orange '70 383 4 speed has the A36 package(3.55's). The car has no power steering or power brakes and it has the V21 hood treatment. I always thought if any Charger would have had 3.91's originally that would have been it.

[TylerCharger69]

Out of curiosity....does that Hemi prototype shown in the picture still exist?   I'd like to see some color photos of it if it does!!!

I don't know if I have one, but I've seen a color pic posted on this site before.  One of the advertisers in MCGuide uses that color picture in their advertisements.  I'll search around to see if I can find a good pic. 

There are a lot of people who would love to find that car, but I don't think it exists anymore.  We've speculated in the past whether you could order a Hemi Charger without the R/T package, and the 1969 dealer's order form for a Charger indicates you can.  That press release car also proves that it could be done before.  I have some real good actual photos of that car (even though they're in B&W), and they show the torque boxes, plus the automatic transmission cooler lines only found on HemiAuto cars.  I am convinced its a legitimate non-R/T Hemicar.

I did see that Geno, but figured it might have been an early addition to the line up and discontinued before production.
Out of the almost 800 Chargers I have in the registry, I do not and have never seen a 69 Charger with the A31 option.....R/T or not
I guess never say never but until I get one in the registry Ill say never

[hemigeno]

Has the "other" Chris logged any into the '70 Registry, or was A31 even listed as an available option that year?

Just like you, I know better than to say always, definitely, or never with MaMopar...   

[Just 6T9 CHGR]

Chris said he has 2 XP 383 & 1 XH cars with the A31 option......all very close in build date

So like the saying goes anything is possible, but not likely, so 323's maybe or maybe not a suregrip was stock....

The 489 case was introduced late in the 68 model year so the possibility exists a 68 R/T with automatic could have a 489. The Sure Grip was optional.

It appears that 318 and 383 2bbl cars with A/C came with 2.76 standard but I do have a 68 Charger tag from a non A/C car with 2.76 and one showing 3.23s.

The 3.55 gears are sales coded to the 383-4bbl cars only so I don't think you'll find a 68 R/T Charger equipped with them but if you want to see them listed on a fake tag I can help. I have several 68 Super Bee and Road Runner tags coded for 3.55's but no Chargers.

3.91's available on 383-4bbl cars 69-71
