69 390 into 66 galaxie convert (help)

I'm a newbie to this site, a newbie to galaxies and pretty green with car restorations in general, so please bear with me. ... I bought a 66 Galaxie convert without power and tranny and bought the engine mentioned above, (engine tag: 390 69 11, 9 F K 311 S) attached to an fmx 3 speed. I'm trying to mount the engine, but it looks like the distance between the engine mount and then tranny cross member mount is longer than the same distance on the frame. Basically, like the engine/tranny are too long for the car. Is this possible? .... I'm told the galaxie last had a small block in it. Since the 390 was an option for this car, I have to think the size should be the same. Any thoughts appreciated. Thanks again.

Update: I found that there's a couple different versions and I might have a truck or van trans setup. I'm going to try and pull the trans codes tonight and see what I'm dealing with.

If your car had a small block it makes sense that the engine mounts and tranny mounts would be different. If it originally had a big block there would be no problem. Check your tranny crossmember and see if it has different mounting positions back or forward. I am not familiar with the 66, but I know some tranny crossmembers had that feature where you could move them ahead or back.

the trans cross member should be able to be moved and the stock tranny mount should line up as for the motor mounts they are not interchangeable you'll need to track down some galaxie 390 mounts 65-69 i think should work but you'll need to do some welding an fabrication.

The motor will bolt in using the correct 352/390 mounts and the crossmember will have to be moved back like what was mentioned above,the 65/66 crossmembers wont move back far enough to use 67 and up trans since the part of the frame the crossmember bolts to is shorter on the 65/66 then the 67 and up. I made a couple 1/4 inch plates to move the crossmember back some on my 65 country squire that got a 67 390 and 67 C-6,when you move the crossmember back you will have to take up the slack in the E brake cables and there is supposively a 66 C-6 crossmember that will work but I have never seen one just heard of them.
