Try Unique Van Crafters on Dequindre Rd. in Roseville (?), Mi. NE of Detroit. 1 586-778-4444. You can get a cap installed for around $2,000. I cannot remember the name of the place, but there is a shop in Wixom, MI on Wixom Rd. north of the Ford Plant that specializes in making vans accessable for wheelchairs etc. I know that they have put the larger door on the back and raised roofs.
