Near the top of the following thread there’s a link to Persh.org which shows the different types of towers/mounts that can be used in these trucks. The main thread shows how I used 67-72 style mounts on my 1960 GMC. You wouldn’t need to do the rear crossmember change if you’re keeping the original type bellhousing with the side mounts.
