Exclamation Motor mount issue

I decided to switch out my motor mounts with some Brown Dogs while I was doing my header swap and I've come across an issue. This is how my driver side mount is seated, passenger side is fine.

Contacted Brown Dog Industries and they were saying it could be the trans mount or possibly that the truck was in an accident. I replaced the trans mount yesterday, didn't fix the issue at all. Carfax is clean and I do not see anything that could have caused this due to frame damage. Car drives straight as well. I was hoping after driving it a bit the mount would shift, but no dice. The mount for the engine side has a few numbers written on it making me think that it may have been replaced.

Need to fix this, any advice would be great since I am unsure on how to fix this. Thanks in advance.

Did you try swapping it out with the other side? Just a thought.

They should be identical.

They are both different, they can only be installed on their specific side.

Currently getting help from Tim over at Brown Dog Industries. Extremely great customer service might I add. It would be nice if all companies were as helpful as they are.

Maybe they're labeled wrong. Hope you get it figured out.

Changing the pass side on my 92. The oil filter bracket is in the way of the bolt. Anyone ran into this?

Yep. I did. Had to cut the bolt and get a new one.

Fastenal is the only place I could get a new metric bolt long enough that was high strength. It needs to be grade 8 or better/equivalent.

I'm glad I went with Iron Man mounts now. They weren't side specific.

I found a random leaf spring, or CA bolt I had sitting around that was a tad shorter. Same bolt otherwise. When I replaced it I put it in with nut towards the back.

I did too. But I didnt have any spares that would work.

Unless you wanna pop off that oil filter housing (you don't, trust me), gotta cut the head off.

Good news, bolt cost me less than $5.

This is what Tim asked me as well. I do not believe my transmission crossmember is backwards, but he was saying that my transmission mount might have been backwards to start with and me replacing it with a new one and installing it the same way did nothing. Here are a few pics of the trans mount:

Ugh this is bugging me so badly. What the heck could it be? I need to drive this thing and I really shouldn't considering I am getting crazy vibrations.
