Large oil pan plug

I disliked the large plug in my truck so much I welded a bung in the middle of it that uses a modern oil plug with O ring.

The pressed steel one on mine is thick enough I don't think I would need to do more them drill and tap. I was thinking about the same thing yesterday when I drained mine.
 
I use something called a "Ford Wrench" that was issued as part of my Air Force tool box back in the sixties. It's a Craftsman No. 44491. Looks like a pipe wrench but without the teeth. When I was discharged, it somehow "disappeared" into my private collection and I had to pay for it....maybe about a dollar The jaws open to 3 inches. Very handy for lots of applications, including flathead oil changes!!!

When I Googled "Ford Wrench", I found these were/are also called "monkey wrenches"! Amazing what you can find out!!!.

I don't like the big style plug. I find when im draining the oil it comes out far too quickly when you remove the plug and the can ive got to catch the oil gets overwhelmed with the volume of oil that comes out and the oil ends up all over the floor.

Get a radiator drain pan. They're bigger than a regular pan and have a spout for emptying. Prop it up close to the drain plug, just enough room to get your hand in to remove the already loosened plug. Let the plug drop in the pan. If the oil doesn't have far to drop, it won't spatter as much.
 
I think the violent rush of oil was a feature, not a bug...but oriented toward real service stations with a big drain and catcher that could be put right up under a car on a hoist. I think the rush (remember, this replaced an earlier pan with regular small plug and hole) was intended to rush some sludge out the door before it could settle. Obviously a problem if you are trying to get the oil into an old roasting pan sitting on the floor 18" above the pan in your driveway...
There were wrenches made for that plug, as noted above, but it never occurred to me big wrenches might be needed...oil changes on the family '48 were done by my Father before I started being interested, and I continued doing them when the car devolved to me. We both used the Ford adjustable that came with the car when it was delivered, and had no problems suggesting need for a bigger wrench. The OEM wrench can only partially grip the flats, but that is plenty since this is a bung plug tightened against a gasket, not a highly torqued fastener.
My Father taught me to run my finger around the large hole to help remove the sludge, which was a standard feature in pre-PCV days.

I use an Apco-Mossberg #748 wrench; they occasionally show up on eBay.

I have two of the Apco-Mossberg #748 wrenches. I also have the differential plug wrench that has 10 (I think) different sizes of square "studs" on it for plugs/bolts with sunken heads, for the lack of the proper nomenclature.
