Hey Randy,

Here they are pass side castin # is 3751074 driver is 375106(could be

8.

I looked them up a while back in galens white book and they showed 73 440hp manifolds, were in the trunk of my X when I bought it. Have single pics if you want, email me.

DALE thanks . the passenger side doesnt seem right ? it looks like maybe a non HP manifold . and the # from what i found isnt right but i dont know for sure the drivers side is correct .

are you keeping them ? or do you want to sell the drivers side ?

thanks RANDY
