Ride height

I don't think height is all that important, as long as

it's even both sides

You have sufficient travel to the bump stops

It's "in the rhelm" of where the caster/ camber was set, IE you don't want to change ride height much after you set caster/ camber

Mine may not be relevant, because I've got a later K and LCA's

Original specs in my 67 manual says 2 1/8 + / - 1/8"

Below is right out of my 67 shop manual
