How in the heck does this thing fit on??? I have a OER Fan Shroud for 67-68 big block, tried to fit it up anyway possible and doesn't seem too. Are you suppose to cut holes for hoses? They seem to be in the way. Is the OER repop that bad of fit it needs severely modified or am I missing a trick?? Is there a chance previous owner used small block raditor? Would it matter?? Assembly manual shows no differance in actual raditor??? Any tips or pictures would help. Thanks
