sub65,
You've got to use the "long box" 1/4's.
They have to be cut to fit. You've got to order the R/fnt, R/rear, L/fnt & L/rear. The front 1/4 sections have to be cut & shortened. Cut the front 1/4 sections about 6" back from the door jamb. cut out the correct amount of the 1/4 & splice back together. This will give you the lip you need at the door jamb. Click on my webshots link below to see. Hope this helps!!
