I am installing an axle with a 2 3/4" diameter axle shaft ( actually 2 5/8" measured) on a 41 half ton. The closest spring pads I can find are for a 3" diameter axle. Will these work? Can the gap be filled in and be strong enough?

O'reily's has universal spring perches. They may fit better than what you are finding.

Try these guys- they have a lot of stuff and they have heavy duty perches, backing plates and U-bolts, so that you don't have to use thin trailer hardware.

They can also make you custom perches, I believe...

Maybe these will work? Jeep perches

I'd just call them- they are very helpful.

Holy Cow, it looks like "perch" is the key search word. Thanks

I like the ruffstuff perches, one of the few places with narrow ons that are also long, not for a trailer axle.
The ones I needed were to fit about a 3-5/8” tube, they wouldn’t custom make them at the time so I ordered some for smaller tube and machined the radius to suit.

Wouldn’t weld a gap, get them to fit real tight before welding in place.

Also, don’t forget to carefully measure and set pinion angle before welding spring perches on.
