67-72 Crossmember swap/Big Block frame mounts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey People,
I am swapping an '88 Sub 3/4 ton front crossmember into a '69 factory Big Block truck. I am concerned about the shape of the late crossmember being different where the engine frame mounts bolts to it. I am either going to use the '72 only frame mount, or a '73 up frame mount. For those of you who have done it, which engine frame mounts are best to use, and does the Engine/Trans. mount correlation stay the same?

Thanks,

Tim
