1968 GMC 2500 Big Block Swap

I'm going to purchase big block frame mounts and motor mounts to make sure all goes smooth, however, do I use the same placement on the frame where the small block mounts are now, or do I install the big block mounts in the set of holes towards the front of truck?
Thanks.

Perfect! That's where they are at now. Easy enough.
Is there a way to tell if it has the big block frame mounts already? I can see them, but don't want to waste money because some of the 68's had factory big blocks.
