............in place of a B/W T-10 and don't modify (lengthen) the drive shaft. The front yoke doesn't go into the transmission tailshaft far enough and sets up a horrible vibration at speed. Just hoping this hasn't affected the bearings in the tranny. From the rust and debris on the exposed part of the yoke, it looks like it has been there longer than the previous owner thought. The 12 year owner before him, had to have it and didn't know it.
Interesting to sort out the history of your car. But, it's also amazing that owners are sometimes clueless as to what they have/had.

There were a few things I found on my car that I was afraid to sort out - bent spindle, mysterious brackets brazed to the frame, a 10 leaf rear spring, and front coil springs so tall the car rode resting on the upper rubber snubbers.

It's amazing that the drive shaft even stayed in place all those years. Probably would have broken the tail of the trans. and come flying out eventually.
I can guarantee that the rear bushing in that Muncie is trashed. Time to replace it and the seal while you'e at it. Glad most of us on this forum learned the basics of physics when we were playing with toy dump trucks in the sandbox. Who on EARTH would think that an install depth 1/3 of the design depth would be ok? CRAZY.
Did not know the Muncie and BW take different drive shaft lengths.
They are the same length. That is not the problem. The input yoke appears to be a short version (used by passenger cars) rather than the longer Corvette piece.
I've read on this forum and other places too, about bubba's working on a car. I guess I now have a 1st class example of bubba work. It almost had to happen before the 2nd previous owner bought the car from a Chevy dealer in 2005 becasuse i've spoken to him many times and he's a pretty sincere guy and has nothing to hide from me. He didn't sell me the car.
Then, I thought maybe the fellow who bought the car from the owner mentioned above, might have changed it out and just didn't want to fess up to it, but from the looks of that yoke, I don't think that couldn't happened in 9 months and 100 miles of use. And again, he has nothing to hide from me. I don't think either of these fellows were lying.
I bought it from Classic Cars of the Ozarks and those are the liars. They knew about the transmission and rear ratio, yet still told me it had a matching numbers drivetrain (engine is) with the original B/W transmission. They bought it off Craigslist from the last owner and it was stated in the ad. Went as far as sending me the "Bring a Trailer" ad and brochure, from when the 1st owner above sold it to the 2nd. Said they sent me the Craigslist ad, which is a lie. There were many other lies I caught them in, but fortunately, the car is a good car and justifies keeping and fixing the issues. Relearned a very good life lesson, because I was too lazy to go look for myself, but to be honest, I didn't know then 25% of what I've learned about C-1's since buying it. Probably would have passed on a worthy car. I just loath liars!

Here's the passenger car front yoke (top) and the C1 Corvette front yoke (bottom), aligned at the centerline of the driveshaft trunnion; the Corvette yoke is over an inch longer to accommodate further penetration of the yoke into the extension housing caused by the Corvette's extreme U-Joint operating angles.

Please post what the exact lengths of the different yokes are. Hard to tell from the pictures.

That's why I aligned the two yokes at the trunnion centerlines for the picture, so you could see the difference - it's a little over an inch difference; the longer one is about 4-1/2", the shorter one is about 3-1/4". It's really obvious when you see the parts in front of you.

if "I" couldn't get total compressed suspension engagement like in the pix, "I" would go with a longer driveshaft

So I went out and measured my slip yoke. Not 3 1/4" Not 4 1/2" but 4 inches even. What does this say about my slip yoke? Is it long enough? Is it in need of replacement with a 4 1/2" slip yoke?
Thanks for any info.
Bubba got to it.
Reminds me of a time in my early years when I had a 1979 Ford F150 that I bought very well used to replace my rust bucket 1973 F150. The three on the tree went bad in my 1979. I had a great idea, I'll take the trans out of the '73 and put it in the '79. Well, the '73 had a 2-piece driveshaft and the '79 had a one piece. Not problem, I mounted a bracket on the '79 frame to hold the carrier bearing (at least that's what I called it). It worked!....Except that the ratios were different so I had very tall gears. I drove it a year or more with no issues. It wasn't my daily driver, I think I had a 1983 Escort.
Then, I sold the truck to a local guy and I don't recall mentioning the trans swap. Maybe I did... For about 6 months, I saw the truck in his driveway and was like--cool beans. Anyways, about a month later, I saw the truck sitting in his driveway with the 2-piece driveshaft hanging down on the ground. I bet he and his mechanic was like wtf went on here?!?!
Yes, I was the Bubba but I was about 18 and it was in the late '80's. Stuff happens on old cars and you never know what you will find. Your corvette was an old car 35 years ago so yes, Bubba got to it at some point.
sorry if this was a little off topic. Glad you found this before it let loose.

This is what you get when you install a Muncie...
