Quoting toybreaker:
Abe,
I've seen a few crossmembers fatigue/stress crack from leaving out the gusset plate on the passenger side.
That suggests that the loads fed into the structure by the control arm/suspension are enough to flex the crossmember past what it can endure over the long haul. Probably be okay for awhile, but I've seen at least two cracked crossmembers personally, and have heard of several others. All the control arm loads are fed into the front part of that "u" shaped crossmember, and without the gusset plate there to spread the load, shits gonna flex.
... and that gives me double the concern on the drivers side.
I'm not an expert, but from just looking at things, it would seem to me that north/south bar works a lot harder on the drivers side. It's doing the same job of bracing the crossmember open "u" section, and feeding the control arm loads into the subframe/chassis, and it's doing it without the benefit of the gusset plate on the other side.
Since the control arm is where all the loads are fed into the chassis/subframe, I think having that arangement as stiff as possible is the best bet for a long trouble free service.
... or to put it another way, deflection leads to wheel hop
... and wheel hop leads to broken parts
Thanks! This is exactly what I needed to know. This is why I put it in the newbies section, I don't know these things, I appreciate knowledgeable answers like this without the newb bashing.

I can understand your reasoning if this were a factory option. But since they built every galant and DSM this way your reasoning is Moot.

Well not every DSM, 2g's came with only 1 N/S bar. Unless you don't classify 2g's as DSMs. That is why I asked though. Also, not everyone runs the intake manifold brace/bracket that bolts to the manifold and block. So it's stuff like that, that I'm trying to learn about. I didn't know it was such a crucial piece, but that's why I posted in the newbies section. To me, the second N/S was a similar piece. Just extra bracing. But now I know better. Another example is the A/C bracket that bolts on to the block. Many people remove that when they remove a/c, but they don't use a spacer or leave the bracket on when installing the half shaft. That's probably more crucial than the intake manifold bracket/brace. I'm not trying to argue or anything, I'm just explaining my point of view on why I asked if it's okay. I appreciate the response, but I don't think it was entirely moot, at least based of these reasons.
That's pretty sweet. I'm definitely going to pick one of those up!
Thanks guys.
