cheapest place to buy oem crx part

i have done some searching myself and found some low prices i guess, low for being oem. anyways i am in need of a front bulkhead basically. I purchased an 87 si and recently discoverd for sure that the driverside frame is bent, so i want to replace it along with the radiator support, headlight mount, etc on that side. a junkyard might be the way to go, i dont know. anyways if anyone knows of any cheap places to buy these factory parts, let me know.
