Yes I would just need someone to redo the inside.If you are mostly wanting to refurb the inside, just a new comfort liner and pads can refresh a helmet.
I don't think I've seen any place sell replacement EPS liners but I haven't searched for it either.
It's not just you.I’ve got my old Puddin Bowl from the 60’s no way would I wear it while riding, it’s just a decoration. I for the life of me can’t understand why some people (read hipsters) want old crummy helmets to ware on there street bike with knobby tires, brown seats and no back fenders, so they can look cool !
Okay, I’m thick skinned, come after me.
