Hey Gang!
I was doing the pinion seal on my '64 yesterday, and while I was under there I took down the driveline numbers and have been going through my reference material trying to decode them (still waiting for my 64 judging manual to arrive). Here's what I got:
Bellhousing Casting #: 3840383 (second digit could be a 9, perhaps)
This is the same number that shows up in Noland's book for a L76 engine with an M20, I've got an L75 with an M20. Was this bellhousing used on both?
Tranny Tag: 3839602
Tranny Casting #: 3851325
Tranny Patent #: 3088336
Tranny Tailshaft Housing #: 3846429
Not sure what these mean, does it confirm that it's an M20? Are there casting dates I've missed?
Diff Stamp Pad: CJ 212 64 (3.08 ratio, Feb 12 1964 - 9 days prior to trim tag date)
Diff Cover/Mount Casting #: (3 or 8)8(3 or 8)0303
Diff Cover/Mount Casting Date: B14 (Feb 14th)
Diff Cover/Mount Other Casting: GM5
Anyone know what the correct casting number is for the cover/mount, and what GM5 signifies?
Thanks in advance for any info that you can share.
Cheers!
