Hello, I know this is a long shot, but I need the hot water heater diverter that goes under the dash that diverts hot air to the defrost plenum. Looking for the tubing for this heater as well. I live in Pana, IL thanks.

Welcome to the site, have you reached out to the usual vendors that may have the part?

Thanks for the reply. Yes I have contacted these suppliers with no luck.

What about Memphis Equipment or Surplus City Jeep? Both have M37 stuff-I've walked the Surplus City yard-plenty of M37 stuff there. And Adirondack Dodge?

Surplus City is no more. They closed a few years ago. MWM bought the inventory. I thought I had the defrost setup here, but must have traded it away. I can't find it.

Thanks-I didn't know that!

There is an M37 hot water heater manual available which is useful for installation and parts identification. I picked up a manual at a show, but Portrayal probably has one.

The M37 diverters are scarce. They suffer rust damage from moisture dripping from the cowl vent. The 2 1/2 ton diverter is similar almost to the point of being nearly identical. In other words, while not "original," I think it would bolt up just fine. Once the hoses are attached, I don't think you'll notice a difference, if originality is important.

I have one of these units that I will part with for a mutually agreeable price (I'm on the road to the Kilroy show and not sure what that price is, but will entertain an offer). I'm happy to send photos after I return.

Hope that helps.

Thanks for the reply. I have the manual for the heater and have looked at the M35a2 diverter but not sure what would be required to make it work. Looks like $30-60 price range for the ones I have found.

Decided to go for it and purchased a diverter for a m35a2. Hopefully the installation isn’t too big of a problem.
