I have your M20 Muncie 4 speed transmission.

Carefully clean the area by the oil filter with some paint remover or lacquer thinner.  Do not use anything abrasive.  Then take some more pics at different angles.  I think I see a hint of some numbers. 

I have done oil pan removals both in and out of the car.  I don't think I will ever do another one in the car.  I know it is more work, but your chance of getting a good seal are better when the engine is on a stand.  Also this gives you a chance to check things over closely and address any other issues you may find.  But how you do it is up to you.  Good luck.

Steve,

I need one Navy blue shirt with print on front.

I read over all of the options.  Very, very interesting.  I also think it is cool that some of the cars were built with "Show Paint Required".  I wonder what was required for that?  Wet sand, buff and polish?

Which I believe is why some of the D90 stripes don't always line up perfectly.

Gary, are there any marks stamped on the top side of this case?

Although I can not guarantee these are originally from a Camaro, they are most likely from 60s or early 70s GM applications.  

I grabbed a handful from the parts bin of used shims.  Had 6 in my hand and 5 were unique.  Pic attached.

I have been looking at the issue with the small c after the assembly date for several years.  It appears that it may be an inspection mark.  I have a few cases with that small squared off c and some without.  Seems like it is more common in late 68 model year assemblies.

that is why when i ordered the car i specified EO to the dealer because i was familiar with 65 impalas that color.

you order by the color code number not the color name

So did you order it by the color name or by the paint sample and code in the book?  Paint samples in books do not always look EXACTLY like
they do on a car.  I am not trying to argue, just trying to get the story straight.

If they are truly from a 1969 engine, they are most likely from a truck or the 396/265hp full size car application. 

I have a low horsepower 396 Impala 1969 engine in storage and I am pretty sure that is what the valve covers look like.

So is it at least POSSIBLE that you ordered what you THOUGHT was this Evening Orchid color, but it was really that Olds silver color?  Because the Olds color does have a VERY SLIGHT lavender hue to it.  And this was 44 years ago. 

I mean if you were just looking at a book and ordering a color, you might have mistaken one color for another - right?

I have seen that Olds color you mentioned - and that is what I believe it is.

Vintage photo shows it as some type of silver with a VERY SLIGHT lavender hue.

Where are these meetings and is anyone invited to attend?  Depending on the venue and my schedule I would be interested to hear what these guys have to say.

Oh, and it would be nice if you answered questions people asked you.

Nobody knows everything - but most of us are willing to learn. 

What is your goal?

The stripes are generally only still there on low mileage original cars.  One orange and one white.
