57 Chevy Wiring Harness & Steering Gear

A Big Hello From Texas !!!! I'm New Here, My Name Is Cliff, I Need Some Opinions From You Guys & Gals ! Needless To Say, I'm Working On A Budget Here ! I Want To Replace The Original Wiring Harness On My 57 Belair, Can Anyone Recommend An Aftermarket Harness Company, Searching For Quality At A Low Price, Also Car Has Manual Stock Steering, Going With An Ididit Tilt Column & Power Steering, My Question Is: Other Than Purchasing A $400.00 Power Box, What Are My Swap Options ? Chevy Vega Box, Etc ?? Is There A Junk Yard Box That Will Bolt Up ?? Thanks All In Advance !!!!!
