Topic: 390 C6 - Transmission Crossmember Question

[carguytroy]

Trying to identify this crossmember or rather make sure I have the correct one for my car. Picking up missing items as I work through putting the Mustang back together. Car is a 1967 Mustang 390 with a C6 trans. Here's a few pics. The numbers on it are 5 11 3 then an "A" with a circle around it. Is this the right thing and what would the factory finish have been? Thanks.

The one you need should have a large ?390? engraved. I think the one you have is likely for a 351/ C6 application.

Looking around the web it looks to be correct. West Coast Classic Cougar shows an example that matches exact. I was told it was out of a 67 Shelby which I doubt, but I'll go put it in the car and see what's up. Were these painted or just bare metal?

[RoyceP]

Not sure what you are seeing but they all were unpainted bare steel.

There are a bunch of them that look pretty similar to one another

There is a close up picture of the same transmission mount shown in the unrestored picture area of the site in the one marked
67 San Jose 390 GTA Fastback - Unrestored Picture Thread
Picture is labeled U-10 on the third page

Numbers you found are the date code and based on your signature it was made a couple of months or so  prior to your car's completion date

A few additional pictures from that unrestored late San Jose 390 GTA. Compare these details with the one you have







Hope this helps

From what I recall the 390 c6 cross member has more reinforcement. The blue one picture has the reinforcement that runs across 3/4?s of the back side which would be for a small block. The 390 version has the reinforcement all the way across from end to end. Looking at the pictures Jeff posted you can see that where the large R is stamped there is reinforcement metal above the R stamping basically creating a channel.

Thanks Jeff!  Now I can sell my one that is painted black and keep my bare metal one.
