I got some used parts from my favorite junk yard. I learned a few things and get to redo most of the job I started and cannot finish till I get paid next week. 90-91 vans use a different booster than 92 up and 89 down. The pedal rod is shorter on the 92 up, I found out the hard way. The proportioning valve that is on the later vans fit my 91 perfectly, I replaced my master cylinder with one off a 97 explorer since I will be doing a disc brake conversion in the rear. I also found out when the rear abs module fails the pedal becomes very soft, feels like a bad master cylinder. I need to buy a brake line flaring tool and a 7 inch dual diaphragm vacuum booster to complete the job. I will update this with pictures when finished
