Need a picture of a 151 heater

[randyscycle]

Hopefully someone with a 151 can help me. I have an M151 heater (just the blower and box) that I am working into my M715. It has a 3" outlet duct off the blower fan.

What I'd like to see is how the stock duct comes off the blower. A pic would be very helpful.

I'd also like to know if anyone knows where to find the flexible duct by itself. Almost all auto parts stores only list 2.5 inch or 4 inch. None of the ususal MV surplus suppliers I have checked will have the duct listed seperately.

As I am doing this, the heater will be mounted under the hood and then ducted into the cab to a box with a flap for floor and defrost, just like a deuce heater.

Thanks to all in advance!

Go to the G838 site, register...it's free just like here...and ther are TMs that cover it in detail.

The heater output went through a diverter box on the M151, so you could direct warm air to the windsheild or floor as desired. Here's a pic of the blower and diverter box:

Thanks Moose! Thanks too Will! That's a handy site!

Here is what I ended up doing this morning. Now with the duct through the firewall (using 2.5") I have a diverter from a Chevy pickup I'll adapt and then have floor or defrost:
