Well, I upgraded my 23 Big Bend rims to the ones I wanted which were the BD Black Steelies. I moved my stock tires to those rims and no surprise it works. However, the stock bump stops no longer were long enough. I bought some of those Quadratecs and those were really for jeeps but whatever, Well, I guess I can't cut worth a dang because I screwed that up. Bought a second round and those fit a little better but the cuts looked awful but who looks anyway? I guess I do. So I'm sitting there thinking of ordering a THIRD set when it occurs to me I have some success with 3d modeling using Gemini AI for assistance. Now it isn't a walk in the park and often takes many, many iterations as my imprecise model language causes confusion, either that or the AI is messing with me or both.

Anyway, I took some measurements and the AI reminded me that the filament Im going to use TPU shrings so add 3mm to my measurements. I used a Prusa Core One+ 3d printer, its very nice with TPU and other filaments I've tried. So I tested printed about 6mm of the form to test the fit of the pin. I also had tried to simulate the concave of the jeep aftermarket model. Later I realized when I find my original stops it if fine flat. So I went with flat. So I got up early yesterday before church and started the print. Fourteen hours, later, I used remote control to turn off the printer. LOL, no sense walking out to the barn in the dark.

Today I checked and they fit so I took the spare off and installed the new stops. I used the socalled Christmas tree push pin as I could not find the original Ford pin without a set of stops. Bump that!
These yellow images are from OpenSCAD using the code developed by the AI and me. My measurements and ideas. The code of the AI. Skynet this ain't.

The last image is from my 3d printer with two of the stops to be printed and it will take 13 hours 51 minutes. It's to print out some useful things instead of silly toys.

Hopefully those are soft enough to not dent your tailgate when you’re going over bumps/rocks.

The Big Bend wheels and BD steelies have the same +55 offset. Your bump stops should have been fine.

The flared base should help with that.

OP mind sharing the file to save me from having to create one? My 0 offset wheels make the factory SAS about 5/8 too short. I have some TPU I’ve been wanting to play with…
