Josh S,
Put a want ad in the classified section here on the forum for the lift bar and mounting plate you need to transfer your IH lift hitch to your dad's 149. I'm sure someone has those parts laying around.
Also there is an hitch installation manual in the Manuals section under "Options" for installing an wide frame hitch on 1X8/9 Series. "Wide Frame 3PT Install" It shows a good illustration as to why there is a bend in the bar for clearance with the fwd transmission mount and because the mounting plate on the rock shaft arm is closer to the rockshaft than on an 82 Series.
