May need engine crossmember and towers for big block - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm swapping a big block into my 69 4x4. The 67-72 4x4's didn't come with big blocks and I've heard one solution that provides better header fitment is to use an engine crossmember and towers from a 73-87 truck.

I assume the 73-87 setup is different depending of if it is a big block or small block but I don't know if that is correct.

In the event I decide this is the better approach, does anyone have these parts and if so, what is your asking price?
