1968 442 parts Identification

...and your alternator looks correct for a '68 A-body car without A/C or heavy duty cooling. It appears the date code is 8C8 (8 which means 1968, C8 which means March 8th). Check that against the build date on your trim tag (located on the cowl, driver side).
I'm not 100% sure on this, but it rumor has it that some 1968 4-4-2s with manual transmissions somehow came with the 7028251 carburetor.

A discussion about anti-seize, lubricated vs non rotational force to clamping force relation, and dissimilar metals corrosion, or lack thereof, is way out of the question in that fitting as well.

Looks like the Canadian built 442 should have the 3:31 rear with the M21 (pretty much confirmed in my 442 rear options post)
So based on my research, I should find HF code on the M21
And RF code on the rear since it has manual brakes.
I have the engine number from VVS which I thought would match the vin. but I guess in 1968 it doesn't.
So the items I plan on verifying as original are:
Engine
Transmission
Alternator
Carb
Rear (obivously, the gears behind the cover could have been changed)
Probably should check the distributor.
Not sure if I have to verify the originality on the Teflon tape
Did I miss anything important or have the wrong codes?
TIA

The engine unit number for a 1968 car is stamped on the oil fill tube. Prior to 1968 it was stamped on the front of the passenger side head. The VIN derivative (which Olds first used starting with the 1968 model year) will be stamped on the block below the number 1 spark plug.

The carb numbers in the PIM were revised 4/29/68. Although no one seems to have an earlier revision to know for sure, it almost surely added the 253 at this time. I've seen pics of only two 253 carbs in 25 years, I've never seen one in person. One was dated 1528 and the other 1718. The 251 carb was used at least until very late in the 68 model year for both MT & AT applications. In addition a service bulletin dated 6/3/68 details the modifications required to the stock MT carb because of rough idle. Unfortunately it doesn't specify the carb number to modify.
