eBay is a good place sometimes. AB Linn sells there. There are places like Fred at Adirondack Antelope Valley Truck parts Memphis Equipment MILITARY SUPPLIER SEARCH RESULTS The web site above will help. If you find a supplier that has what you need or want at a price that is acceptable you can...

The axle shafts are not, never were, ductile, grey or any other form of cast iron! If you think they are, you're clueless as to metallurgy! If you're breaking axles you either don't know how to drive! Or you're slapping a questionable used axle back in without finding out what is wrong. In most...

The M37/M43 rear axles are not weak! They were never made with grey cast iron! People are often clueless when it comes to the problems that have plaqued a few M37 axles. I've seen a lot of conversions, engine and otherwise, that were so bad you wonder just what the **** these people were...

M37's and M43's fronts are passenger side drops. The rear ends are shifted to the passenger side as well.

I know what you're going through. For the little I drive the M37 4X4 or the M37 6X6 each year which is probably less than 1,500 miles each. I just can't seem to justify the expense of dropping in a 4BT. We're going to New Mexico, Wyoming, down to Southern Colorado and then up to Montana this...

Let me help you with some of the Mopar stories that are flying around. The 383 is a B block engine and not an RB. There were two unusal years in which the 383 was actually a "Raised Block" engine. If you can find one it is either a 1959 or 1960 year and rarer than hens teeth and not worth...

Even though it is made primarilly for diesel applications, I've used 15-40 for years in gas engines and have never had a problem. The M37 230 flat heads are low compression engines. I doubt you'll ever run it hard or long enough to ever have any neglible effect with today's lower zinc oils...

Here's a kicker, they weren't originally made for the M37. They were made for the WWII Dodges which the 3/4 and 1 1/2 Tons used the 230 engine. These were made for depot rebuilds on these trucks which were being sent to Korea and lendlease countries that wanted the old trucks. Given the low...

The LA and slant 6 engines from the late 50's and through the 60" used the same hydraulic clutch bellhousings. The two transmissions in use were the NP420 and NP435 which both used the same length input shaft. There were two commonn sizes, a 1 inch 10 spline and 1 3/8 inch ten spline. The...

Some thoughts to consider. If your block and radiator are this bad, your freeze plugs are also leaking or about to. They are not that difficult to remove and reinstall. I would remove them and then proceed to to flush and use air pressure to blow out the chunks and antifreeze that has turned to...

On the side of the Dodge V8 block is a series of numbers with either a 318 or 360 cast on it. This will tell you which engine is in the truck. If it is long and straight with the spark plugs and wires on the top it is a flat head six cylinder. If you're unsure about the differences get someone...

All the way up into the 6 to 8 mile per gallon range usually. Santa congratulations, that is phenominal. I had a CJ2A that had one of the Phillipine replacement bodies on it and bought a kit to install a 2300 Pinto engine in it. It was really nifty. Guy had just had the engine rebuilt in his...

Mike, I have a bunch removed from M37s. Email me your address and I'll send one on to you. The best way to mount them is to remove whatever studs are still in the transmission case and use regular 3/8 bolts just long eough to go through the case and either cut a new gasket or use some of the RTV...

The gearing in the stock US M37 PTO is different from Power In to Power Out. The direction of pull should be that when the PTO handle is forward you are taking in cable to move the truck closer toward what you have connected to the end of the cable or pulling what you are connected to closer...

Isn't it always so much fun to work on old iron and bring it back to life. You're doing great. Check the gear oil in the differentials. If it is black and smells kind of peculiar you'll need to drain and replace it and in all the gear boxes as well. I have an extra wheel nut socket if you need...

The stock brakes on an M37 do require more than the usual maintenance to keep them performing satisfactorily. They are undersized and basic in design compared to today's standards. I'm designing a full set of disc brakes for my 4X4 and have been busy on other projects but hope to have them...

Won't work at all. Please box them up and send them to me. Great find. They are getting rare as far as the originals are concerned. I've seen where there are a couple of folks making new sets. One which is so good apparently the parts are interchangeable with original Warns. If I didn't already...

He may of broke a bit of sludge or other debris lose from inside the carb and it's now drifting around inside your carb or lodged in the jet opening. If you're careful you can take the cover off without breaking the gasket and look inside to make sure it is clean and remove any sediment and junk...

I'm trying to remember who used to sell them all the time on ebay. They usually went for around 9 or 10 dollars. I keep a spare just in case one gets borrowed permanently, I misplace it, or it gets broke somehow. Had this huge old large wrench that I figured I'd never use. turns out I drilled...

Perhaps he'll get the idea that NDT and NDCC are not hardline designations that are always molded into tires but a way folks describe the style of tires.
