RPO Z21 included rocker moldings, wheel well moldings and driprail moldings. Also pinstripes.

Thanks Rick, I found at CRG that the 3K is the code for RPO Z21.

Well, I think I've got my original transmission for my 67 L30 car finally Grin
 The numbers on it don't seem to match what Stillwater Camaro was suggesting though. I sure hope it's the one. All the casting date codes are Dec. 66 and I believe the assembly is also the last day of Dec. So this should have been applied to a 67 car.
 I am making three different posts incuding this one with two pictures each so you guys can check it out.

The maincase casting shows to be a '66 casting #.  The rest are 67.

No, they are all 1966. Correct me if I'm wrong, but the CRG info clearly shows how to decode casting dates. All three components, case, side cover and tail housing were cast in Dec. of 1966.
 That's  L 19 6 and L 14 6 and L 21 6  All December of 66. And then the whole saginaw transmission was assembled on the 27th day of December 1966 for a 1967 model year car.
 That is how the CRG website describes how to interpret theese numbers. Is the website wrong?

I was looking at Colvin's BTN's.  He has been off on some things and I don't claim to be an expert on this anyway.  I'm just showing what he says about the side case #.  According to him it was used for the 1966 Model year not the 1967 model year which is different than the cast dates.  That's not say there wasn't some kind of holdover on certain casting numbers to the new model year.

Ok, thanks for confirming that source for me 68Z. That is a book that is on my to get list. I noticed that the CRG page also has only one casting number for a 67 Saginaw ending in 032 but other members also have 67 cars  with different casting numbers on their Saginaws'

 Thanks again Jeff.
