never seen any measurements for starting with a bare chassis, but if you haven't taken out the bellhousing cross member, you can still do as I said above and get the positioning of the aftermarket trans and engine mounts by measuring from there .... note that installing that engine mount cross member can make your stock e-brake linkage not work, so you may need to shift a bit forward and/or modify the mount .... and you'll still need a fan shroud
