It is the same as your 78 except the bolt pattern on the bottom - unless the 77 was from a 25" motor. Then the bolt pattern would be the same. 2 bolts on each side were in slightly different places.<br /><br />Why not just put the 200 towards the right parts? Especially if the guy sells you a 73 instead of a 77. They look the same but are totally different.<br /><br />Be careful!
