The case number is 3890564, side cover is 3890527 and can't make out the tail shaft number and cant make out the dates if the last number is a 5 or a 6. Thanks Ed

OK, I did find a trans that's close but have another question. On the bottom where the usage is stamped below the side cover, instead of the usual R9A26 being stamped, this trans has R1130. I know the R stands for Saginaw 4 speed but what does the 1130 mean?

It gives me some options, as long as I can get it close, I can live with that. I bought that trans for $100 and it has a single grove on the shaft so it's the right gearing. But now that I have a few options, I'l keep my eyes open and continue reading the site blog. Thanks for everyone's help.

It is a 6 on the side cover, photo was a little fuzzy. But what I'm looking at are these the proper casting numbers for that time frame build? And who's to say these wasn't service trans installed under warranty sometime early 67, But I'm looking more at the casting numbers. Thanks Ed

I have no intention of racing it or beating on it. That's the whole object of putting it back to original is there are so few of them remaining because they have been converted to Muncie. This one does have the proper Saginaw, just the wrong year Saginaw

So more than likely 3890664 would be the main case for this car?

What your saying is the number that CRG has for the main case number is wrong. This is where I'm getting a little confused. I'm getting mixed answers. The cars build date 10E was actually Monday Oct 31st so the car was built the first week of November. Therefore the case was most likely cast sometime in August or September and the trans would have been built somewhere between Sept and Oct of 66. Everything on this car checks out to be original except the trans, muffler and tires. I know these were notorious for being blown and then switched out for a Muncie. At least one of the prior owners that blew the trans put a Saginaw back in it. You mean to tell me there are no original L30/M20 cars out there to verify what trans went in to it

Thank You, Ed. I'm the third owner. the car was in a dirt floor barn in northern Wisconsin for the last 15 years. Surprisingly there is very little rust on it. some minor swis-cheese in the trunk floor and a couple of 1/2 dollar holes on the bottom of the rear inner wheel wells, other than that just a lot of surface rust on the under chassis. It was repainted back in the late 70's or early 80's. Who ever did the paint job did a really nice job cause the only thing I might do right now is repair the upper valance where its chipped and buff the rest of the car out. It's a black car with the original black vinyl top,with a few small rust bumps at the back bottom of the sail, but no dry rot; black & white interior with the back fold down seat. It has the full factory console gauge setup with the Tac in the dash. I got wind of it through the grape vine and made a move on it. I guess right place, right time. I didn't steal it but by far didn't over pay for it. Thanks for asking, Frank

All 6 cylinder motors had a 3:11 first gear and the L30 trans for V8s was a 2:54 1st gear

I'm new to this site and not sure how to do this, but here goes. I've recently picked up a barn find M20/L30 RS #124377N1XXXXX in the upper Midwest with 38,000 miles that seems to be an early car that the 4P was not on the cowl tag. Cowl tag says built 5th week of October. It has a MK date proper block, heads and intake, 3.55 10 bolt PK code non-posi rear end, dealer installed radius rod (dealer welded bracket right over the date code). Also has the original carb and shifter were in the trunk (has a Holly and Hurst on it right now) The problem is like most M20/L30 cars the prior owner had blown the trans and replaced it with a 1974 Saginaw 4 speed trans. I real would like to put it back to 100% original but need to find out what the proper numbers are for the trans. CRG lists the main case number (3915032) but nowhere could I find what the proper side cover and tail shaft numbers are. I have a line on a date proper 6 cylinder 4 speed that has the case number but not sure it the side cover and tail shaft are the same numbers V8 trans. I know the gearing is different for a 6 banger but I would rebuild it with the proper ratios.  Any help would be appreciated.
Also, Thank You. Your site is a world of information and has helped me a lot. Keep up the "great work"
