Default C-Beam?

Are any of the C-beams that connect the rearend to the transmission the same or are they all different?

I am suppose to have an automatic C-beam out of one car and a 4+3 C-beam out of another car, but they look the same.

They are different, I'm not sure what the differences are, but they are different.

They LOOK the same??? Put them next to one another! DUH! The automatic is longer. There are only two different "C" beams, and you have one of each.

RACE ON!!!

Big Mike:

As you can see, one of the CF's acknowledged experts found out many years ago that the slight difference in length of C beams matters in distinguishing between them. I hope the rudeness often displayed in answering simple questions doesn't make you or anyone else regret asking a question. I wish some experts would just not answer a question rather than trying to make one look like an idiot.

Actually, I don't perceive the person asking the question as being the idiot.

It is one thing to not know the difference. And it may be necessary to know, to do a job. But to have a sample of each, available, where, the poster can state."but they look the same", is the HEIGHT of rudeness and laziness. Give one of them a kick to line them up and LOOK!

Dang. I decided not to jump on the bandwagon earlier figuring maybe you had a bad morning or something, but now you do it again.

This is way beyond your usual gruffness into aholeness.

Maybe he doesn't have one of each. That's why he asked.

Even if he was an idiot, which I am not seeing, you don't need to go so overboard about it.

Wow you have a simple mind to believe that you are the only individual with the level of intelligence equivalent to that of a monkey, but thank you for restating the obvious.

Any multicellular organism could have created such a difficult test to compare the two beams. Having already done that test ( see at this point you are already behind, catch up ) and more to compare the two I came up with the conclusion that these two beams are the same. So, after the first response stating that the beams for auto and sticks are different my next conclusion would be that the beam sold to me with the parts car was not the correct one.

Thank you Steve9899,
you hit the nail on the head.

BTW, in 84 the C-Beams were identical for either the automatic or 4+3.
It wasn't until the Dana 44 rear was installed on the manual trans car, that the C-Beam was made shorter due to the nose length of the D44.

Correct. The difference in length (and the location of the bolt holes) is due to the difference in the size of the Dana 36 and Dana 44. The 44 is bigger (farther forward), hence the beam is shorter. I have an automatic transmission in my 94, but I have the "manual trans" c-beam because I installed a Dana 44 rear.

CFI-EFI, some of my threads that you've responded to seem to read like you think I'm an idiot. Give us a little more credit.

JMHO, take it for whats worth.

I would simply like to say that CFI has provided me with a great deal of very excellent information. He's always been ready to help and respond. We all have our own little quirks and disagreements. Electronic written media, such as this forum, do very little to impart the spirit of the response. My advice would be to judge on the basis of the quality of the information and take the context with a grain of salt.

Well stated. Given the options, pleasantly wrong advice won't do me any good.

Yes, CFI-EFI is one of the most knowledgeable gurus we have on this forum. He has helped a lot of people a lot of times, including me. I was grouchy that Sunday morning as well, so i complained of how he came across. no big deal.
