Gerahead's 71 Dart

Yesterday I got the upper control arms and the "bottom" side of the k-frame POR'd and then overcoated with a couple coats of gloss black. I also got the steering knuckles bead blasted, painted with etching primer and painted with Cast Blast. I think it all turned out really great! I have tried unsuccessfully to find replacements for the white foam seal that gets sandwiched between the knuckle and the front brake backing plate. Anyone have any ideas where they can be found? I am considering trying to find a similar sheet material and making by own. What have you guys done to replace these seals? The lower control arms and strut rods are next!
