Thanks for the tips and replies Chopper and Ldub....

No one that I've dug deep enough to talk to at Isuzu dealers or parts departments can find a way to get a replacement for the larger foam seal that WAS attached to the inside middle of my damaged VX bumper cover. The repair shop, which is an Isuzu dealer, had gotten a new bumper cover but it did not have the foam seal and they don't know anything about it now.

The two other foam seals near the front impact bar and radiator I think I found part numbers for (8972160750) and perhaps can be ordered.

Thing is, neither of these foam seal thingys were damaged in the accident but they were removed by the shop and trashed. Not sure why, I mean, if they were there to begin with when the car was built...then they served some purpose and should not have been removed...DUH. Might be my loss, I don't know yet. But the new bumper cover's appearance certainly does not seem as "high quality" as the original, it's weird but looking at it that's what I think. Lesson is...keep what you got!?
