Title: Bolt through the motor mount
Post by: Bolted to Floor on July 29, 2017, 01:26:32 PM: Can anybody post a picture of how they bolted through the motor mount? I'm having second thoughts on how I went about it.

I drilled through the mount and tapped the plate that sits against the frame mount. Ran the bolt through from the block side and left it flush with the plate.

I'm not having luck finding a post, much less one with pictures that still works. :o and I haven't taken the time find a new hosting setup either. ::)

Thanks guys

You need grade 8 bolt/s and grade 8 nuts at the minimum. I tried it using a single bolt and nut, and on the first run, the nut backed completely off. I then drilled the bracket and mount for two bolts, and solved the problem. The bolt should come in from the top, and install the double nuts on the bottom. Joe-JDC

What is your experience with them and what car/engine have you fitted them in/on?

I got them for my 67 Fairlane on recommendation from a friend who's building a 66. Haven;t installed them yet myself but he said they were spot on for fitment.
I used to do the bolt through the driver side motor mount on my Mustangs when I was a kid. I welded the nut on.

Last time I modified some SBF mounts, I just used 1/8" steel and welded straps to the mount to hold the pieces together. You're basically defeating the NVH part of the mount, so don't half-ass it. Make it strong, or just move on to motor plates.
