Suburbans are life

Thanks in advance to anyone who might know. I've been searching and searching for the little black plastic bracket that holds the engine oil cooler lines in place. I bought a used 1998 GMC suburban K2500 with the 350 cu.in engine. The lines were leaking at purchase and after some searching the cause was that bracket being broken. I've tried different trans cooler line brackets off of eBay trying to find the right part and no luck. If anyone knows or can point me in the right direction to finding one, it would be greatly appreciated. I've done way too much work to this truck to be defeated by a piece of plastic. Thanks again.
