Does any one have a picture of the correct big block exhaust manifolds for a 71 up truck.

Here is an Ebay Auction with the correct styled manifolds. Date correct no, but the style, shape, and location of where the exhaust pipe connects is. Your 71+ manifolds could differ by a few things. 1) no air injecter holes at all 2) plugged air injecter holes 3) air injecters in place (usually 72+ from what I have seen) lastly 4) a continuous web of cast iron connecting each exhaust port (better and less breakage prone like this auction) or no web between each port.

mine are the same part numbers as those on ebay. I just hate using headers.
