| | | | Joined: Mar 2018 Posts: 139 'Bolter | | 'Bolter Joined: Mar 2018 Posts: 139 | I have a 1951 3100 and have a different 3 speed transmission and rear axle. The case number is GM 15, 3354726, E245 and the tailpiece is GM 8, 8866722, E226. The rear diff is another story. I looked for numbers but only could find the front passengers side has a F1 (stamped) and the front drivers side has a cast 331 and a clock face. I’m hoping members can help solve the story of this trans/rear axle. thanks | | | | | Joined: Jun 2011 Posts: 5,096 Crusing in the Passing Lane | | Crusing in the Passing Lane Joined: Jun 2011 Posts: 5,096 | Can you send us a picture of the trans. and diff?

I’m using an IPad Pro and don’t know where to find the picture size to see if I exceeded the size limit. I took pictures of the transmission and rear diff. Help? | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | 1. You have to learn how to downsize your photos to 300K or less.
On an iPhone or iPad, you can accomplish this by mailing the photos to yourself, and choosing a smaller photo size.
2. However, iPad/iPhone photographers: unless you can read/save those email photo-attachments on a computer/device with a file-directory/file-manager, you will not be able to "select" your photo-file OR drag-and-drop your photo-file using the Stovebolt image/photo Attachment Manager.
If I am incorrect, would an iPhone/iPad user please tell us how to attach photos here (from an iPhone/iPad)?
Added/edited later: there is now a "Files" feature in Apple iOS for iPad/iPhone. It works with the Stovebolt image/photo Attachment Manager.

I haven’t given up yet! | | | | | Joined: Mar 2018 Posts: 139 'Bolter | | 'Bolter Joined: Mar 2018 Posts: 139 | I found a number on the pinion gear. #3740674-10-39-GM. Also a 2-12-57.. Does that mean it is a 1957 rear end? | | |
