Looking for old 1.7.10 mods but can’t find them

I'm trying to put together a modpack for old 1.7 mods but I can't find a good chunk of ones I'm looking for. Is there a place or archive of old Minecraft 1.7.10 mods?

Especially ones found in Youtube videos (like DanTDM and PopularMMOs) from back in the day that have broken links now.

I know Curseforge has a few but not all of the ones I'm looking for.

I'd love to find the mod from this video again, for example:
