modified timing chain cover

[looch353]

I am doing a conversion with a 77 stingray and a 1994 lt1 engine, I need to find a timing chain cover that does not have a hole for the water pump and/or the distributor hole. the water pump is converted to an electric and the distributor is now in the rear of the motor once again. However , a standard timing chain cover will not fit and I am pretty sure some company makes the modified cover ..does anyone know where to find it ??????
