im doing an 8.8 swap with a rear disc setup out of an explorer and i was wondering if the 4 wheel ABS explorers with drums used the same proportioning valve as the ones with discs. i would look in the explorer shop manual at ford but i dont have one laying around at the moment

With rear ABS it doesn't really matter, the ABS system will keep the rear from locking up for you.

thanky sir,

your the man :afro:
