Here's how the po installed one on my truck. Mine was born with a six, that's why there's the 1" bar between the rad and the core support. It was a real challenge to get the thing on and off - in retrospect I think the "easy" way would be to leave the rad on the core support and take the core support off the truck (with the rad still on the core support) to install the shroud (if it fits your v-8).
