Get a picture of the cover plate on the back of the center section....
 
Probably an 8.25 which WILL NOT fit your 65 without a lot of work to the rear end
 
I have no idea never saw a flat side to the pumpkin with a tube out of it before.
 
It appears to be a B body 8 1/4, but it's a terrible picture for identification. If it's a B body axle, it will have to be heavily modified to fit in an A body. Narrowed, spring perches moved and "all that".

Since you have a 65 Dart (great choice BTW!), any 63-76 A Body rear end - 7.25/8.25 or 8.75 - is a bolt in. The 7.25 and 8.75 use the SBP 5 on 4 wheels the same as what you currently have. The A Body 8.25 (73-76) uses LBP 4.5 on 5. Hope this helps a bit.

My dart currently holds a 7.25 that i know of, and i have heard alot about that rear end being kind of shitty if you wanna make power.
 
Would be nice if you know the gearing before you buy. For example the 8.25 i bought has 2.73. Gearing is useless for my particular application.
So on top of buying rear end, the gearset needs to be purchased as well.
That one there definetly looks like 8.25.
 
im sorry for the bad pictures, its the only one he send to me. thanks for the answers

It's ok. Maybe you could get him to send you a picture straight on from the rear cover......but I wouldn't worry with it. There are more choices that will actually fit your car.
 
I sold a complete 8.75 to a member in Germany. I crated it and shipped it to his container forwarder. He received it a couple of months later. It can be done.
 
Remember you will need a different driveshaft and shock pates. Do you have a flange on the back of the trans the driveshaft bots to?

Since it’s a 65, chances are he has the hall and trunnion. That can be worked around when changing the rear end

im doing a full convertion of the gearbox, driveshaft and rear end. i got a new made 833 OD 4 speed, and are currently making a new driveshaft.

That's definitely a 70's 8.25. (note the two ribs on the housing like your picture)
You would have to have the tubes shortened and get new axles plus move the spring perches before it will fit your car.
On the upside, Jeep Cherokee's and lots of other newer 4x4 vehicles have sure grip units that fit in those cases. (I know because I just did one)
Those same vehicles have gear sets in the 4.10, 3.55 and 3.73 range commonly and cheap.
THEN even the disc brakes from the Grand Cherokee or Liberty bolt right onto that rear end.
The carrier bearings are different between the newer Jeeps and these early 8.25's but they are easily sourced, and I have the part numbers for them from when I did mine.
I also had to get longer wheel studs because the rotors take up more of the stud than drums.

This is a 1973 8.25 Abody unit with Jeep Limited slip and 3.55 gears with Grand Cherokee disc brakes.
It's in my 73 Swinger right now and I'm really happy with it.
