I have one on the floor of the shop right now, I’ll get you an answer in a day or so

A trade that you can enjoy and personally benefit from is a good trade.
That being said, I enjoy my M38 much more than my M37 because I can drive it while the Dodge still has a list of things to be fixed longer than my arm..

I would like to see pictures of the inside, if it has the data plate on the glove box that may be helpful as well, although they were frequently swapped… my M37cdn has a glove box door from an M43.
Any Canadian markings on it? Does it have a tailgate?

The Canadian one is the one on the roll back right? At least the camo on it certainly looks like what you see on trucks from the prairies. Can we see some more pics? If you take a look on the drivers front frame rail, on the top just before the bumper you should see some stamped #s Should be somethi...

Alright, once the tailgate is on for good I’ll direct some attention to getting that center support fitting properly. Today’s job was taking a break from bodywork and instead, fixing the fresh air vent on the cab. It has always been kind of loose, and it turns out the reason for that is that the pas...

Looking good! Those are some big tires. Take some pictures when you have it out!

Last of the tailgate pics About the center support for the tailgate: Mine sits a bit low and doesn’t seem to do much. Has it been flattened? Off the truck the part doesn’t look warped, but on the truck it just doesn’t seem to sit quite right. Does anyone have a picture of theirs they could share so ...

And finally, today’s job was some work on the tailgate. What I was starting with was fairly straight, although there were cracks in all four corners, the hinges had seized, and the top right corner had a fairly significant bend, and a crack where the metal had folded. So, with some pipe clamps, some...

A couple more pictures- The black paint is just to protect the fresh metal for the time being. We have been getting some pretty large temperature swings, and bare metal will flash rust if not covered. Once I’m done the welding I’ll be doing some sanding and smoothing so that the large imperfections ...

Well, time for another update! I have been trying to make a push to finish up the bodywork and I am finally at a point where I’m seeing the end of the rust. I’ve just about finished welding up both rear fenders, with only the outer passenger side to do still. As most of this was cutting and patching...

Yes. You will have an easier time if you first pull the distributor too so you can look down the hole to see where the slot is pointing, then drop the oil pump just enough to rotate it one tooth. Then replace the distributor, matching it with the new orientation of the slot. If you don’t pull the di...

Finally some update. I had the same problem with the toolbox. Seems to be a great place for humidity to accumulate and do its job. Had to replace almost its entire floor. Winter, at least in cold places like yours, it's the perfect time for making progress. Hope you jump in and update us soon. :-) ...

You're correct, it belongs inside the cross member. At least the fix is just nuts & bolts, better than something done with a torch & welder... Ok, thanks for the confirmation. 4 bolts, cotter pin, big nut! I can do that! With everything found out over the last 4 weeks I will suspect everyth...

Nope, not a typo I clued into it when I read the data plate, that the Canadian spec is in imperial quarts/gallons and not US.
So, 4 imperial quarts is roughly 4.8 US quarts.
Only slightly less than what the American trucks call for
