Brake booster boot

Anyone know where I can find a dust boot for the push rod that connects the brake lever to the power booster? I have tried the Chrysler dealer and was told that it is no longer available....you have to buy the entire booster to get it. I've also tried a couple of the auto stores but to no avail. They must be out there somewhere because they're on all the new boosters. I'd be willing to purchase a used one in good condition if anyone would have happened to have changed out their booster.

do a search on junkyard dog. They search hundreds of boneyards across the country and each one that has your part will email you with price.
