Actually I was referring to the transmission mount above. It hasn't come in yet. I might take some pictures to show how different some mounts can be if you don't do a side by side comparison assuming I get the right one this time. |

I was hoping to avoid doing anything radical. Hopefully when the next engine mount arrives it will be dimensionally like the one it came with. Otherwise it's back to the drawing board! |

My 77 AMX was already a V-8 and I was sold the incorrect trans mount when I swapped in a 401/727 combo. I just cut off the wrong portion and welded on the correct taller mount on my new trans mount. They were a lot different.

Yes, I appreciate the quality of the mounts and how easy they were to install. Had I gotten the correct transmission mount I'd have had little to no trouble. These 6 to V8 adapter mounts look a heck of a lot more durable than regular V8 mounts. I researched them and no one had ever had one break or fail. |

FYIY I designed the mounts and the fixture and consumable welding pieces. We keep sharp track of all the components and the fixture. I can tell you they will fit with 98% certainty. I am glad it worked out for you.

I already had two holes in my motor mount and they lined up with the jig just fine. I didn't know it had two holes until I pulled the engine so I had already bought the drill jig. I found the problem, and it was with the transmission mount. Apparently I got sold the wrong one. The old transmission mount appears to be about 1 1/2 inch taller. Doesn't seem like much, but it took the engine off of the firewall once I put back the old tranny mount. I bought this one at Advance so I'll take it back and get the right one if possible. I appreciate the input from everyone. I just felt it had to be something simple, it usually is! |

Did you use the center hole to align the drill jig or did you use the end of the drill jig on the end of the pad?

The transmission mount is new. The engine clears on the driver's side barely. Problem is the seam on the passenger side just to the right of the blower motor mount contacts the rear of the engine at the head and especially the valve cover.
I was thinking about the possibility of the engine mounts somehow being slightly off and to the rear too far. I had heck getting to the rear valve cover bolt on the inline six. Once Bulltear's forum is back online I plan to ask there to see if there's an issue I've overlooked. Oh yes, one more thing I found out by chance about this car. It's a Canadian AMC. I can't imagine that this matters though. It did have the Canadian electronics for the original distributor for one example that has no bearing on this issue. To my knowledge there is nothing different about AMC cars sold for the Canadian market. |

Usually any issues like that are from the tranny mount. IIRC if your trying to stuff a 727 in there youll need to bang the firewall to make it fit due the tranny tunnel
