Saw a rain cap that bolts to the fording exhaust pipe extension listed on eBay, said m38/m37. I have never seen one on a M37 and wanted to ask the accuracy of the listing. Is this correct for an M37?

listing is wrong it is not for m37, his is 2 3/8" the m37 ford pipe is under 2"

As far as I know there is no such thing but I did install one on mine it was for a tractor but it works fine.

The M37 never used a rain cap. The precleaner caps on the M38, 38A1 or the M151 will not work. All use different size pipes.

I use a basic tractor type too, I can't remember but I think it is 1.5"...Decided even if it wasn't original it was worth having, after every rain when I started my truck it would become covered in black droplets

i saw that one on ebay,,,,,,see the end price, over $100 wow.

I plan on just using a tractor type.

From what I know about the Jeep crowd, it must be a key piece to have...but I like the tractor part price better. I also noticed on Whalen's M37, that he had a breather cap on his intake. Both would probably make sense for long term installation.

The breather cap is another tractor part. Absolutely essential for the grain farmer to have. Having your tractor inhaling grain dust and chaff during those many hours of harvesting could cause untold damage to its engine. It also serves to keep water (rain, snow, sleet) out of your air intake.
