Wilsons Sandbox

When installing progressive spings I've heard some differing sizes for the spacer to be cut down by. Is it either 1/2 inch or 1 full inch.    Got my order of brake line, disc protector and skid plate form Fred today. I was impressed by everything and highly recomend his services, at least as far as parts go !?!      Thanks again Fred!   Thumper John word to your mudder
