Original 67-69 Camaro driveshafts - information requested about your car

[Everett#2390]

As you say, my theory also, anything is possible.
Here I have two shafts from'67 L6/PG/2.73, and one from '68 V8/PG/3.08 - don't know the application of those shown - over 40 thing
Shafts measured from shaft yoke to shaft yoke, overall
Short one is 50 inches overall by 2 3/4 inch diameter
Long one is 51 3/8 inches by 2 inch diameter
Critical speed is dependent upon OD, wall thickness, material, and length.
Just my theory.

Some of the Firebird Turbo 400 driveshafts also had inline yokes. I have one in my garage.

My 68 maybe Z28 is an 07B and the shaft has yellow and white paint swabs. The yokes are in line.

Thanks Chris, for Z28 I believe should be orange and white stripes. Faded orange can look like yellow.

Can you get a measurement center of u joint to center of u joint?  Thanks!

49.96 is the length for most 67 and 68 Driveshafts. The other one is too long for any stock 67-69 Camaro.

Are you sure on your tube diameters or are you measuring the yoke?

Just adding to the list of offset driveshaft end yokes. My 68 definitely had the offset U joints. Z28, M21 with a 4.88 rear ratio. Built late Dec 67 or early 68. Can't remember. 124378N3561xx.

I know the Driveshaft Report is out but I want to share information on my original owner 1969 Camaro SS L78 with M22 transmission.  The car is
02D (1969).  The driveshaft is not phased and the markings are Orange and Blue.   The driveshaft has never been removed from car and it is very low mileage.  I'm sure of the color makings.  It uses straps at the differential.  Differential is positraction 4.10 ratio.

I also have another original owner 1969 Camaro SS L48 with M20 transmission.  The car is 11C (1968).  The driveshaft is phased and the markings are long gone.  It uses straps at the differential.  Original owner but high mileage.   Differential is positraction 3.70 ratio.

 Question......my 67 LOS L35 w/TH400 has the original driveshaft with the nylon injected yoke and trunnions .....do you think that these can cause issues from age?

I certainly think that is possible. I love originality but when choosing between that and safety, safety always wins. You could put it on the bench and do a careful inspection to see if anything is loose before replacing.

Hello all, hope someone can help me with my confusion. I've ordered u-joints from 2 different sources, based on the vehicle specifics, but when I got them, the first ones didn't fit the pinion yoke. Reordered and then they didn't fit the driveshaft yoke. This lead me to read through the CRG driveshaft report, several times along with this 14 page thread. I thought I had the original correct driveshaft, but know I don't think so. The car is a 68 10A L35/TH400 car. The 12 bolt rear has a pinion yoke that takes straps and cap screws, with 1.06 dia. bearing caps but the width is @3 1/2". Cant seem to find a u-joint with the correct dimensions. If I've read the resources right, the driveshaft should be 49.96" length, in-line yokes, with HD u-joints (at both ends?) If this is correct, I'll need a combination u-joint at the rear that has the wider, large diameter caps on one axis, and the smaller 1.06 caps with the same width on the other? The driveshaft I have is 49.96, has small standard u-joint on one end, and TH400 yoke with injection molded HD u-joint at the other. Any help is appreciated.
