Big Block / Small Block mounts

[DRD57]

I'm working on a 68 Chevy pickup that has a small block in it. However, it's mounted in the forward holes of the cross member leaving several inches between the engine and the firewall. I believe this is the big block mounting location.

I plan to move it back to the proper location but, I'm not sure if the steel brackets between the rubber motor mounts and the cross member are the same for both locations.

Are there different brackets for small blocks and big blocks or do the same brackets work in different holes in the cross member?

Thanks,

Don
