Large Boar Armor

[supersaiyandoyle]

I'm creating fantasy large boar armor for combat and plan to use the horse armor listed in Low Tech; what should the cost and weight modified to to accommodate the smaller body size?

This is the percents for those who don't want to have to dig up their Low Tech (Pg. 117):

Caparison: A flexible armored blanket (cloth, scale, or
mail) covering neck, torso, groin, and legs, and reaching
down to the knees or even lower (protects the legs on 1-4 on
1d). Also called a trapper, it sometimes has a hole for the
saddle. Cost and weight are 500% of human torso armor.

Chanfron: Head armor, protecting the skull and face. It
can be made of flexible or rigid armor. Cost and weight
are 50%.

Crinet: Protects the neck. It can be made of flexible or
rigid armor. Cost and weight are 50%.

Crupper: Plate armor protecting the hindquarters and
upper legs. It protects the torso on 4-6 on 1d, and the hind
legs on 1-3 on 1d. Cost and weight are 150%.

Flanchards: Plate armor attached to the saddle, covering
the flanks. It closes the gap between crupper and peytral.
Flanchards protect the torso on 1-3 on 1d. Cost and weight
are 50%.

Peytral: A rigid plate that protects the torso from the
front only (sides and back are unprotected). Cost and
weight are 100%.
