Dave when you find a current supplier for correct material, please post. Thanks

My Z28 had a broken tip Oil dip stick I did a lot of research & bought a nos green tip I changed the oil & Put a long Gm Filter & 5 Qts of oil! Question Oil just shows at tip didn't these come come stock with a short oil filter so should it take 5 1/2 qts when you use the long filter? Tks Bill
Here is my TH400 tag:
The 445 date puts it approximately at March 20th 1967 and my cars built date is April 17th.

Thanks for the replies.
Here is a pic of the tag. The paint is gone from the tag and all that is left are the stamped numbers.
Car was built the first week of April. Julian date on trans tag indicates March 2nd....is that an acceptable date range for an 04A build date?
The second digit of the year on the tag is obscured by scuff marks that's why I really wanted to find the VIN for proof of originality. Based on the other info on the tag it looks like the original trans. It's a '67 SS/RS L35 convertible. I plan to sell the car soon and I need proof that it is a numbers matching car.
So far it's a numbers matching car except for the engine block. The trans is the only remaining question left. I cant see if the stamped VIN is somewhere on top of the bellhousing. I plan on buying one of those inexpensive borescopes to get a better look.
The question is why are the U-joints out-of-phase?
The answer is for reducing vibrations.
Graph the power through a single U-joint and a sine wave is drawn. The joint speeds up, positive arc, and slows down, negative arc.
Add another U-joint and its power graph will have the same sine wave.
Add the two sine waves, if they are in-phase on the same shaft, and amplitude doubles, meaning the resultant twist is noticeable.
By offsetting one joint by 30°, decreases the amplitude of the associated twist, less vibration.
Now, driveshaft's having been built forever, and 1st Gen driveshaft's are different from typical design, may be due to the extreme angularity of drivetrain design on Camaro, i.e., wheelbase, length of shaft, OD and wall thickness, and critical speed of driveshaft.
Critical speed is important - it is rocket science. JMT's
Does anyone have any info on the driveshaft for a 1967 L78 4K Camaro? Trying to verify mine.
