I just measured the WMS to WMS of the front of my 40 Ford car. I forgot I had installed a Magnum 4 in. dropped axle years ago. My Magnum axle is 3/4 in. narrower than the stock 1940 axle. The stock 1940 Ford axle measures 48 1/2 in. king pin centerline to king pin centerline. So I think I may have to add 3/4 in. to the 56 1/4 in WMS to WMS measurement (56 1/4 in) I got. That would make the correct OEM 1940 Ford front WMS to WMS 57 in. Is that correct? Wish I had a stock 40 axle to double check. Sorry for the confusion. jim
I think you will have to be more specific, Web Management System, Watershed Modeling System, Warehouse Management System, what exactly are you referring to?
If you had been paying attention to discussions like this you'd realize that WMS is "Wheel Mounting Surface". You know..............that place that is contacted by the wheel when it's put on the hub. Frank
I guess I am too much of a dinosaur. We used to refer to that as drum to drum. Never have gotten used to texting.
I did find a 1998 Ford Explorer XLT rear in the junk yard with disc brakes. It measures 59.5 WMS to WMS They have 8.8 rears with 31 spline axles. HAMBER 35PontiacCoupe really helped me with that as per the following info: "Late 90's Explorers are 59.5" with discs. They're pretty cheap and easy to come across. The Explorer 31 spline 8.8's are dang near as strong as a 9" and they're quite a bit lighter. Actually, I think the early 90's explorers have drums on the back and would be the tough 31 spline axles. They'd be 59.75" (to account for the thicker drums) and would be easy to find as well. You could build one for almost what you'd pay for a narrowed 9". Of course, they'd be 5x4.5" though...
I see your avatar is a 40 coupe. Is it possible for you to measure the front WMS to WMS to double check my calculations? I used short pieces of angle alum bolted to the brake drums as shown in photos and then subtracted width of angle leg.
