Big Block

[eddie1]

I realize there are a ton of threads dealing with installing a big block & I think I have read everone without finding an answer to my question. I have a 63 1/2 ton, I have added a crossmember from a 80 1/2 ton. I have notched the frame to install the stock motor mounts from the 1980. When the holes line up on the top of the frame rail the holes do not line up with the crossmember. When the holes line up with the crossmember the brackets sits about 1/2 inch above the top of the frame. What is the solution? I am thinking mount the bracket to the top of the frame rail & drill 2 new holes in the crossmember. What have others done? I want to spend as little as possible (don't we all) & I prefer the look of the factory type brackets over the aftermarket tubular style.
