My 52 M38 front and rear drive shafts have different type slip joints and different spline counts. Rear is 16 spline with a thread on cap. Front is 10 spline with a crimp style cap. I would like to identify what the front shaft came on and get a new cap and felt, and be sure it will work correctly. Any help is appreciated.[/list]

Both front and rear on both the M38 and the M38A1 are 15 spline + keyway on the factory blueprints for original shafts. You'll need to offer photos of your front shaft and offer up any numbers found on the shaft before any of us can be expected to help you ID your odd front shaft.

I am moving your post from our long term project following "Projects Forum" to the more appropriate "Technical Knowledge Base Forum".

I seem to problems figuring out how to post photos on an iPad. The number on the shaft are ORD 7974675 ASSY. Below those there are these
DGB R32 3175

I was able to load a photo in my gallery.
Thanks

Did you take a photo of the Number?

There difficult to see in a photo. Here they are
ORD 7974675 ASSY
DGB R32 3175

Thanks

I already copied your numbers from your last post. The reason I asked for a photo of the numbers is because how and where they are presented helps provide clue's to the parts identity. So if you cannot take a photo detailed enough and put it in your album then at least provide us with a precise description of the appearance and location of the numbers. For example you can draw a crayon circle around them then take a closeup photo.

See if you can find a driveshaft shop near you. Or else post the spline diameter on here. Driveshaft parts in the aftermarket are rarely listed by make model year. Only by size. If I have the diameter I can probably get you a part number.

He has already given us the Ordnance Supply part number 7974675 that he found on the shaft. That shaft PN was introduced after the end of production for the M38 but it is listed in the ORD 8 SNL G-740 dated 1956. Quite sure it is not aftermarket.

I brought the shaft inside and with a better camera I was able to get pictures of the numbers location on the shaft. Hope it helps. The photo is in my gallery “Richlep2” Still not sure how to attach photos to the post

The URL for your photo is placed between these: [/img]

You then copy your photo's url and paste it between these

There is still only one photo in your album. The original you posted above.

Posting photos from your album:

1. right click on the photo in your album and select "copy the image link" (of the photo) that you want to post.

2. Put (paste) it in between these: . You can use the button tag and "close tags" or you can type them manually.
The [img] without the front slash has to be first and the one with the front slash has to be last.

3. Done!
