I'd really appreciate it if someone knew where I could purchase the support beam that runs underneath the trans.
The front trans. mount is bolted to this metal brace, I've searched high and low for the name of the piece to no avail.

I have my car almost completely rebuilt from the accident I had back last year in november! This is the last piece!

look in the body parts catalog

 

Thats the site i bought most of my replacment parts from.
I've looked throuhg the body catalog, they dont show any pictures, do you know the specific name of the part in question/?

 

yes, it's the transmission mount, if I'm not mistaken Find the lancer you own, go to Engine/Transaxle>Engine and Trans mounting> Trans mount and then select auto or manual.

you can also call a stealership and find out exactly what it's called and ask them how much they'll charge to get one. Then laugh and hang up and order from that site or car-part.com mitsupishiparts.com is run by Walker Mistu (IIRC) but it's like a totaly separate company so the parts guys at the dealership have nooooo idea what you're talking about if you inquire about an order.

good luck!!

 

The trans. mount when illustrated (#9) in the pic seems to be the actual rubber mount the trans. is bolted to.

I'm looking for the frame piece that the rubber mount is bolted to

 

That's a pretty friggin good guess when I'm sitting at work I just checked the service manual and it's referred to as the "centermember" <-- yep, one word.
