Thanks Pete....the only thing I might change is the top cover for the toploaders I think were originally a zinc finish, and not natural.  But curious what others have seen.

I have only found bare steel preserved under the grease and grime. At the very least the bare steel would seem to be the more typical.

I agree with Mr Gaines, I have only seen bare steel.

Nice job Marcus

I have only found bare steel preserved under the grease and grime. At the very least the bare steel would seem to be the more typical.

+1 as mentioned in a number of prior threads

Noticed on page 3 the following

"Typically the top cover has a LM stamping on it and could have been hand marked with either the transmission code or the last few digits of the VIN to help match to the car during assembly."

Have you found some that did match the VIN?  If so do all of the examples follow that pattern? Maybe just a coincidence, like when the last three of the VIN  match the assigned rotation number.

Something to consider - if it were the last three digits that would be the only example that I know of where they used that practice since all the other identification was to the rotation number and something we see on some San Jose installed engine and transmission assemblies. Also on the line the rotation number rather than VIN is more noticeable since its written on the body to be seen at a distance on located in an easy to find location on built sheets as well as many years and plants written largely on the bottom half of the page to stand out

Just thought it would be worth mentioning

Jeff,  Thats a good point actually and makes more sense to be a rotation number rather than a VIN number especially at that point in the production line and build process.  Although....if you think about it some more.....not sure why the rotation number would be assigned to a transmission ahead of time anyway.  I would think they would just pull a RUG or GAZ unit and be done.  I will update the wording a bit.....

The rotation number on at least San Jose built cars when it is found or applied was applied at the car plant not the transmission plant once the engine and transmission were joined. Nice, on top and in fairly large print so that the whole unit found its way to the right car.

At other plants a copy of the buildsheet is attached to the transmission and engine combination with the hand written large rotation number of the upper left hand corner of the form visible. In any case workers where ever they worked adjusted to that plants and shifts typical practices.

Well done Marcus!

 A few notes from personal experience -The D0ZR tailhousing I have only found on big block applications for Mustangs but was used on small block applications for the Torino bodied cars.  The 390 Mustang transmissions RUG-M's and the RUG-AD's are 28 spline. If it was made with 31 spline it would have needed its own code. May want to also mention the D2AR-CB case has a prevision for the seatbelt warning sensor.

Ken....good input thanks.  I think I will actually add something in there on the seatbelt warning sensor since its such a unique piece and design addition they added to the toploaders.  I will do a revision and update in the next few days.

Why isn't 67 covered?

Originally this started as a Hurst shifter and transmission guide for 1970 to 1973 and then changed a few times and eventually dropped the shifters all together, that I will cover separately. 

In order for me to fully cover the 1967 model year I would need to add references to the RF C5AR-7006-D main case that would have been used in 1967 and not the C8AR-7006-D where it starts now.  I can probably do that

Thanks Marcus.
I can send you the paint marks I found on my original 67 GT350 trans (vin stamped).

Yep...that would be great.  You can send them thru here or email me directly marcus@anghelrestorations.com

Would guess the same reason 64-66 isn't covered. Might add another 50% of pages to the article since you have to cover different  shifters back up wire routing, brackets, arms ........

I AM a trouble maker!
It took me some time to source the information in order to revert back from a Hurst conversion to stock. Piece by piece.
But the data would be invaluable.

Updated this now so it covers 1967 t 1973.  New link at the beginning of this topic and here.  Also added details and photos on the 1972-1973 cases with the seat belt warning switch and some other minor changes. 
Thanks for everyone's input.
