Question

Are there any differences between the rear post mounts on an M715 and the Kaiser civilian JTruck?
*the JTruck rear posts are: front 7/8" post, rear 1" post.
*the M715 or DRW?
How about the spring and shackle bushings, the same?
*JTruck rear spring eyes: 1 1/4" for the front eye and 1 3/16" for the rear eye.
*the M715 or DRW?

Are they interchangable?

I know the front post mounts are different due to heavier and wider front springs.

Elliot, I have an M715 sitting right next to a 58 Gladiator out at my place. I'll check for you this weekend if no one else gets you the answers.

I have never noticed any difference between the civy frame and M715 except all of the additional bracing/gusseting, different bed mounts, rear pintle hitch through beefed up rear crossmember, and different steering box bolt pattern.

I appreciate that Pascal.
Might check to see if the M715 has an extra reinforcing plate at the backside of the post mount. Maybe the M715, civi JTruck and DRW are all the same at the rear.
I'll dig through some pics, but thought I'd seen a backside plate on an M715.

***Edit- Here's the backing plate of the DRW post mount:
(note the '70 6 bolt rims are not split ring!)



The M715 post mount backing plate looks a little different for the front of the rear springs:

Looking forward to what you come up with, most important thing being the size of the post for a match.

Pascal if those are a match (I think the front/rear 7/8-1" dimensions were actually reversed) we'll need those cut out with at least 2" of frame remaining on each side of the eight post mounts since he also needs the fronts. 2" if it's a clean cut, lil more for an oxy cut.
Emailed you with my phone #... any questions give me a call.
TIA

Say Elliot, is that plate welded to the top and bottom of the frame in the pic above factory?

No, it's a cheasy repair/beef-up job and he's stripping that and going through the whole frame to restore it as best he can.

BTW, Jim if you are reading this, he verified that even the 1970 DRW earlier style rear hub/brake drum assembly is different from the M715 D70 drum/hub assembly. Possibly on the M715 they built the drums as removable by itself to speed combat repairs. That would make a nice conversion assuming the axle lengths are the same.

Elliott, I'm reading and anxious to get my truck back so that I can check out the rear drums. I wish I had been paying more attention when I removed the rear wheels to get the various measurements a while back. I'll get you a pic when I can.

Why go from "ultra-rare brake parts" to "very rare brake parts" when with a litte more effort you can convert the rear to disks? Looks like it would be fairly easy for the rear - I have no idea about the front.

I'll try to get you some details on the rear spring mounts. I have all three of them here.

The front springs and mounts on the 715 are completely different from anything else. They are not post mount. It is spring under with a box type mount, similar in arrangement to the Waggies, but with wider springs/wider spacing.

Unfortunately, I did not have any posts accessible to measure diameters, but I suspect they are all the same.

Here are some observations comparing the rear spring mounts on a 68 M715, 67 J3000 (5000GVW), and 67 Dually:

68 M715
forward post mounted on large plate, secured by four rivets, post thru frame, reinforced on backside



67 J3000
forward post mounted on small plate, retained by four rivets, post not thru frame, no backside reinforcement


67 Dually
Mine is identical to the J3000. Not even beefed as shown in the frame pics posted by Elliott. I've wondered about that. I am tempted to use the much beefier 715 frame when I redo mine as it also has extra reinforcement in the critical area of a wrecker (just behind the cab).

ncjeepers, are there other differences in the frames? Mine looks good so far but you never know what you'll find when you start looking.
