New Omega owner. 1978 Omega SX
Hello Olds enthusiasts. I just bought an 1978 Omega SX and am real excited about my new toy. Its a fairly clean car. This is my first Omega. I am very familiar with g body cutlass but I will be asking alot of questions to get my Omega looking and running right.

Looks really nice! I don't think an Olds motor ever came in that generation X-body, but I "think" you can use T/A mounts to make it work......but don't quote me on that.
To use the T/A mounts you would need SBC frame mounts and the T/A engine brackets.....if that's a viable option.

You need the frame mounts from a 1975-1979 Omega with the Olds 260. Use Anchor P/N 2328 motor mounts with those frame mounts.
I'm guessing the Omega mounts will be tough to find. The X-car subframe is very similar to the Camaro/Firebird subframe. You might have better luck getting the motor brackets from a 403 Trans Am and using the matching Chevy-style clamshell frame mounts.

Sorry, Randy, I missed your first post when I wrote mine. Yes, you were correct about the T/A mounts.
Unfortunately, you were incorrect about the (non) use of Olds motors in these cars.
The 260 was a factory option.

I had forgotten about the 260 (even though I have owned 2 of them) and never even put it together in my brain that it was available in the Omega.

What trans does car have?
Im am researching that the 78 SX came with a 350 or 200c transmission. The stock engine thats in car is a 231v6. How can I find out myself? I picked up a 200r4 but if car has 350 trans in it, I will keep the 350 in until I get 200r4 rebuilt. I will be pulling the 231 out if a few weeks to put in 330.
Thanks.

A few years ago I bought a rocker moulding I thought was for my 74 Omega But is lighter and about 7/8 of an in. shorter.I suspect it's for a newer year omega.Could you give me a measurement on yours?

I just happened to have mine handy. The 75-79 rocker moulding is just about 77-1/2" long (2-door). Also the face is just about 3" wide, with about 3/8" mounting flange on the bottom.

Has anyone ever compared the two sub frames before? The camaro and the X-body 75-79? They seem almost identical.
railguy, maybe a 4 door car or a car without the wheel well trim vs with or even a K-body cadillac? Just guessing a little.
