You're in for some excitement if you drive the NDTs in snow, and especially on ice. If you're running stock rims, the STA Superlug Mud & Snow 9.00x16 seems to be the default choice for non-NDT tires, at least for ones that are currently available. I bought a set to put on my spare rims, seeing a...

justme has some great advice.

The Army had some less-than-intuitive ideas about how to organize information.

Do you know what "lubricant" is in the steering box now? Over the years people have put anything and everything in these boxes, depending on the advice (good and bad) they received and what they had on hand. Since the correct lube is actually a worm grease such as Mobilgear 600XP460, if it...

ORD 9 refers to "NC" National Coarse and "NF" National Fine. It does mention UNF, as "Uniform National Form". The history of thread forms is an interesting and convoluted subject, but the basic idea is that the Unified thread is a slightly updated version of the old Ame...

What is the best coating to put on the carb to protect it from corrosion? Are you concerned about internal or external corrosion? I've never seen a carb rust on the outside (or inside), since these are made from a nonferrous alloy (aluminum, magnesium, zinc). But Eastwood makes a spray product (Car...

I don't know the grade of steel used for the OEM bars, but I'd try a higher carbon or alloy steel than "mild steel" which is probably a low carbon steel such as A36. Since I have some in my shop (and it's readily available through metal suppliers), my next choice would be 4140.

If you are doing old crusty tires yourself, one of these bead breaker tools is a big help (no idea if this brand is good or not, the link is just an example of something similar to the tool Tim had): https://www.amazon.com/VEVOR-Heavy-Duty-Breaking-Easy-Operated-Tractors/dp/B0C9ZRMXZC?th=1 I think ...

1) Inflating: Is the danger mainly when the bead is not set? IE: Do I need to worry if I put air in a low tire or I'm airing down and up after an off road trip? Yes, the crucial window is during initial inflation after re-assembling a rim and lock-ring. I've not seen a lock-ring rim disengage the l...

Plugs are 14mm. The stock waterproof plug is an Autolite AR5S (alternate number is 2243), which is a cold range plug. These were also available as AR4S / 2242 (colder), AR6S / 2244 (cold/medium), and AR7S / 2245 (medium temp). Champion, and possibly other manufacturers, made similar waterproof subst...

...and the lower lip of the jerry can keeps the bottom above the bolt heads. Gary I'm not a jerry can expert, but is that true only for the vintage USA cans? I have some newer cans that are supposed to be NATO spec, and the seam is recessed into the can body, so the bottom is essentially flat and t...

Can someone tell me or show me photos how the passenger side jerry can holder works? My truck didn't come with one. From what I can gather, I need two rear brackets and a front bracket and this bolts to the standard lower can holder that is used on M38s and other vehicles. So I need 3 m37 specific ...

There's nothing special or particularly difficult about an M37 clutch, but time required will depend on the tools and equipment available and your experience level. I'd allow a full day if you've never done one before.

The head I've been working on most recently is a Plymouth 218, casting 1326304. The as-cast volumes range from 76.2cc to 78.6cc (the TDC hole in cylinder No. 6 was plugged flush with the chamber roof), about a 3% variance, so not too bad. The torque plate was a quickie job, so the finish on the side...

I assuming that you want to be able to take a known Ordnance part number, and see all of the OEM Chrysler and common aftermarket supplier cross-reference part numbers? I recall an Excel list of something similar for the M37 parts, but don't remember where I found it. It wasn't complete by any defini...

Andy, good to hear that things are moving on the engine project again. Looking forward to seeing the measurements on your block. My engine is still not assembled, unfortunately. Last thing I was doing was cc matching the cylinder head chambers, but I've been busy with other work in the shop, includi...
