It's time to sort out the front leaf springs on my '33 Plymouth. I think they may be originals, and are sagging a bit. I've also put a heavier engine in. I'm not finding off the shelf stock replacements. The springs are 1.75" wide. I'm considering buying a set of trailer springs and basically combining leafs from my originals and the trailer springs to make useable packs. I just had Eaton build me a pair of custom leaf spring packs for the rear and I'm very happy with them, but don't really want to spend that kind of money again... Thoughts?

Longest trailer springs are 30" with about 4" of arch https://www.sdtrucksprings.com/trailer-leaf-springs Same people sell auto springs so might see what they have close to your need
I’d think it depends on what they came from, unless you know their rate? I’ve seen short narrow springs under trailers that would probably shake you to death.
I might have a 33 spring if ya wanted to add some leafs. It’s a slow process but the individual springs could be hammered with some more arch added.
I have replaced the front springs on my 33 Plymouth with ones I had manufacture at a small truck spring place. They gave the exact size that was on the original spring. The only issue I had was that I did not have enough arch in the first set, took them back and they re-arch them. This place was located in Portland, Maine.
If your main leaf is good, not cracked or broken. No reason in the world to not use whatever leaves you got. If sagging is a problem you can add some arch too.
Personally, I would not use trailer springs except on a trailer. Lot of other options out there... I used 2 new(speedway) model A/32 style springs on the front of my sedan. What length do you need? There are a bunch of ready made springs out there...
