Leaf spring question

[Joe R]

Hey guys, not sure if I should put this here or suspension but thought the year specific boards might be a better place.

Well long story short I found that all my springs in my heavy half have been heated to be lowered and now I need to replace them. Front coils arent a big deal but the rear leafs are killing me. Since its a heavy half it has 7 leaf spring packs in the back, and they are a fortune to replace with new ones.

Looking for opinions on my options.

I could get a set of junk yard spring packs off a 3/4 ton or if I'm lucky another heavy half.

I could buy new ones for like $400 a side, ouch.

This one I'm not sure of but can I use a 4 leaf spring pack from a 1/2 ton or do I have to change the hangers and mounts too?

Either way its gonna have a 2/4 or 4/6 drop in the end. So being able to hold extra weight doesnt faze me. I only pull an old trash trailer to the dump on occasions with it anyways, everything else is normal driving.

Thanks in advance for the input.
