Home stretch on the motor mounts

This front transmission mount is giving me new respect for fabricators. What looked like a simple bar with a bit of angle iron on it has turned into quite a project–especially for a guy who doesn’t know how to weld.

I had planned to tack it along the bottom of the frame horn but that proved impossible because of the thickness of said subframe–plus the angle iron welded to the top of the one-by to serve as the bracket. There was about a quarter inch gap between the pieces.

So I had to make new stand-offs to match it up–harder than I thought.

Started by drilling through the bracket and putting a self-tapping sheet metal screw through the bottom of the frame horn on each side–the idea being to snug it up as well as possible to measure the gaps. That took a while working under the car.

Next, welding in the standoffs, cleaning up the frame for new welds, and bending new angle to make “ears” to weld to the frame horns opposite my trans brackets.

I think with the car on the ground and the engine installed, the proper loads and stresses on the frame horns will be there, and then the bracket should be welded to the horns.

Of course, to make that happen I need either very tall ramps or a pit under my garage.

For now the sheet metal screws should hold everything in place. I’ll take the whole thing to Mike at the muffler shop and let him do the final honors.
