Harrisons came in chevys ... early heaters were clamshell style rounds

They show up on eBay and are very close in look to the denso... as well as Bosch and the Brit stufff like Clayton

That one is most likely 50’s

oh, I’ve got a clamshell. It’s going In my LV.

I only posted the Harrison to show another vintage aftermarket heater.
 
what heater is this? part two

since the other thread is closed, i'll start a new one. assuming it's a heater...haven't really had time to tear into it. since it's a softtop and there are the remains of a fan on the dash, i kind of figure it's not an ac unit;)

Older thread and these posts are old, but my ‘64 FJ40 has the exact same heater. I always thought it was an aftermarket heater, but after seeing these posts I assume this was the stock heater?? It works great, but I’ve been wanting to get a smaller heater bc this one is rather large, but if it is original……

Thats a aftermarket heater.

This is the first Toyota installed heater in FJ40/45s in the USA market, probably the smallest besides the Clam shell heater.

I wasn’t sure where to put this but I didn’t want to start a new thread when I could just add to this one.

I finally found a clamshell for my ‘63. However it’s a Nippo/Bosch version. Does anyone know if the Nippo/Bosch version was ever used in early LC’s?

I’ve included some pics and would appreciate an estimate on value to see if the price ($450) is reasonable for the condition?

So…I’ve found that there’s 2 versions of the Clamshell. After I read a ton of old threads I still can’t verify is the Denso or Nippon-Denso the earlier version? Is there a serial number I should be looking for on either one to verify it’s correct?

UPDATE: After talking with several more knowledgeable guys they told me Nippon-Denso was never used in Early Toyotas. So the only correct Clamshell heater for early 40/45’s is the Denso version.

I would not buy that for $450.00. It’s in rough condition.
 
@Unimogguy I may have one in much better condition. A denso unit. I'll go look through the boxes and get back to you. I swear there was another on hand.
 
Revive-ing this thread a bit. Im redoing my 1966 Box heater and it is similar to these Hupps but with a brand name of Arvin, does anyone know if the fan blades are pressed on or if there is a set screw that secures it? As Always Thanks in advance

If there was a set screw I would think you should be able to see it? It might be my eyes but it almost looks like there’s a flat spot on the blower motor shaft for the fan? It’s the 10-11 position on a clock. However it might just be the pic? Is there a set screw in that position?
