non abs work from 89? This type of abs was used in 89 and 90. The part is not available new, most all cars use a vacuum booster instead of this electric pump. It was also used on some Buick's and Oldsmobile's, but the part is just not around. How difficult to replace this with just a normal brake system from an 89 or 90, or for that matter, any nearby model year of Caddy?
