Upgraded engine support?

Hello all,
I noticed that there are two different versions of the engine support that bolts to the motor mounts (#4):<br>

The two part numbers are:
901.115.011.03 and
930.375.011.01

It appears that Pelican only sells the 930.xxx part number.
Does anyone know what the difference is, and where the part number is on this piece?

If I have the early one, should I get the later bracket for my engine swap ('77 930 engine in '75 chassis)? It's reasonably priced and I'm wondering if it would buy me some extra security.
Thanks,
Colin

Not 100%, but it should work. I used the cross member (#4) from my 2.7 for my 3.0 and it works fine. The four bolt holes in the middle of the x-member are the same pattern.
