I want to make sure I am right on this

Since my 73 was/is a mostly basket case, I only received one motor mount. Now, until today, I just assumed it was just It was one of vert motor mounts I needed. Then I realized, I have no idea if this truly a vert mount. The reason I’m now questioning my earlier belief is that, I got more than just 73 vert parts in those baskets, some of which I’ve put on this site for ID. None of those were for a 73 Mustang.

So, here is a side pic of the two types I have, with the one on the left from my Coupe, and the one on the right from my vert parts box. Is that a vert mount? I know you cannot be 100% sure, but it is quite different on the engine attaching metal flange part. When you clamp them down on the engine attaching segment of the flange, you can tell the coupe one from the vert one in that the edge of the clamshell actually almost touches that same surface. Thank you for taking a look at this.

Two things, the first I recommend that you buy the concourse bolt kit. Using hardware store fasteners don't have the gripping surfaces that Ford designed for. The build/assembly manual has notes in many places that specify no substitutes on certain fasteners, these were likely dot/crash tested or something. But the notes are there, I've built three cars from boxes. And it's worth the expense of having the fasteners ready at each phase. Ok, said and enough.
The next, the convertible motor mount issue has been researched and they are different. Look again for articles on this. I don't remember all the details, but you have touched on some with your questions.

Thanks for the insights. I bought grade 8 bolts, thinking that would hold back all 150 HP of this monster lol.

I’m still hoping to get a vert owner, who has his engine out, to setup one of his motor mounts to see if it matches the one I have. With no markings on these things, it’s a complete crap-shoot to know what I have.

I had a classic car shop do a lot of work on my 73 vert and they found bad motor mounts. They ended up with 72 motor mounts, engine side and frame side.
