Thanks for the quick reply.

Found that the w/s contacts the support bracket so we had to switch it around to miss the corner of the w/s.

It's a good motor that does great if you keep water out. Most of you know I don't care for the fender mounted heater personally, is very much in the way of access to the left side of the engine. I guess my view is from a mechanics prospective, anything that makes maintenance access tougher is not on my + list if there is a way to avoid it. Many ways to install better than NOS heater systems out of the way & at lesser cost than these NOS units. My outlook is why make life tougher than it has to be?

I agree with you Charles on this one, I got the oem kit on both my trucks for years (bought NOS for $180 in 1997) and I totally hate it.
it's true it's a pain to reach the left side of the engine for maintenance with it.
Now after many years the blower motor seized up, though it kept telling me he was going to do it for two years. (it whined like a siren when on)
Got a replacement motor (Thanks Bill L) but I'm thinking of removing the whole thing and relocating it under seat or under dash (instead of the glove box that I don't use).
I even hate the defroster duct, cause it's always on the way and it's very dangerous with all it's sharp ends.

I may end up selling the whole setup and replacing it with a modern heater.

So if you are not going for a 100% original truck, AVOID IT.

Just my 0.2

Thanks for the feedback - would anyone have a picture of their motor cover ideas? While we want to stay original, the truck is going to be driven so we'd want to see about protecting the motor. Keith

We fab our covers from a length of exhaust pipe tubing of the correct diameter with a plate welded into the top end of it, light weight yet rigid enough to do the job well.

Is the external cover over the heater housing (big rectangular box) and the point where the duct connects necessary? Besides keeping water off of the system, what does it accomplish?

(Translation: I ain't got one - should I fab one or forget it?)

That cover Is for Isolation purposes, it's wood inside and sheet metal outside.

I like the look of it, so it'll be going back on mine, but, It wont be hooked up, I'll put something more modern under the seat.

Other than the fan waterproofing there's no operational problems with the oem setup. It heats the cab very well so I see no difference between a modern setup and the original. Just the mounting place.

mine enver did a good job heating the cab... I wouls have to let the truck sit and warm up first, otherwise, it would never put out enough heat to get warm during the trip. Mabye there was something wrong with mine? It seems to make more noise then heat.

Do you have a T-stat?. You always have to wait. In winter I have to use the canvass grill cover otherwise it only's heats the cab when you are driving at highway speeds. You get downtown traffic and it cools down to a useless point. I think it's because of the Diesel repower.

What's winter in Argentina? 40's maybe? You need to come and visit me in Iowa this winter and we can go ice fishing or something...Thanks for taking care of my guys again. Hope all goes well. Bryan

I just hoped you were coming down this time, but you chickend out again and you are sending that crazy guy Quinn
It's a pleasure to work with you guys down here.

Yes our winters in Buenos Aires, are a joke for you guys in Iowa. But some years ago I've travelled a lot with my M-37 and reached the end of the world (Ushuaia) in plain Winter, just with my cab heater (and the canvas cover of course)

Hey, there, bpj911! You have to remember something. Juan has just gone through the worst of winter and is well into spring, now. He's south of the equator, so the seasons are the reverse of what we're accustomed to up here on the top side of the planet. When we're complaining about the cold (and brass monkeys) up here, he'll be moaning just as intensely about "how damn hot it is."

Yes I know that Argentina is in the southern hemisphere so they are just warming up down there. I am sending some of my guys to work w/ Juan again this time in Chile. I hope you are ready Juan, I think that Quinn will be coming back...
