I have a dana 300 and i know it is off of a CJ. that is all i know about it though.

i dont know if it is the short or "long" version, and i had a interested party ask me today if it was off of a 3 or 4spd tranny... as far as i know that doesnt matter right? i just told him 4spd for the time being.

my question is this, is there any difference between the cases that were mounted to either a 3 or 4spd?

iding the 300

The length of the 1980 Dana 300 is ~10-1/2", as measured from the front input face to the rear yoke face. The later version is ~11-5/8" long. The front input flange for Jeep versions is round and uses six 3/8" mounting bolts through to the transmission flange. The front and rear output yoke is a 1310. The output shafts are 26 splines for both front and rear outputs.
As for 3 or 4 spd it does not matter. It can be "retrofit" to about a dozen Chevy, Ford and Dodge trannys. An adapter is needed for many swaps and can be found from Novak Adapters and Advance Adapters.

The Dana 300 was only offered in CJs from 1980-86. During that time there were 4spds and 5spd transmissions, no 3 speed. So yours, came from either a 4 or 5 speed. There is no difference in the tcase- they were all the same from the factory.

Marine man is correct- you can get an adapter to mate a Dana 300 to just about any transmission.

thats what i thought, had a guy ask me that who is apparently interested in buying it. thanks guys.

how about the adapter? will that fit both the 4 and five speed trannys?
