header question
 

There are some edelbrock tes headers on ebay say they are for a 87-91 burb. Specifically ( Edelbrock headers with y-pipe part number 6865. Fits 1987-1991 chevy suburban four wheel drive automatic transmission and 5.7 liter 350 engine.) but they look pretty close to the ones that I need for my 82 2wd blazer. Does anyone know if they will work? I know, it's not the same part number but it looks REALLY close.
