I need the bracket that bolts to the engine that connects to the round part of the dog bone mount on the driver side. Can anyone help with that? Ive looked everywhere and the only thing that comes up is the passenger side bracket, it seems.

 

Should be 24503458

Its discontinued though. Will probably have to get from a junkyard. I presume yours broke at the ears up by the dogbone?

 

Yeap. Ive always been so careful with that one to.. I think the engine mount being bad for so long caused it.

 

Lol well having that part number you listed helped a bit. Found a couple for sale. Haha give me a break, 80 bucks! Ill go get one myself for $5.






This one wouldnt fit would it?

 

Thats a major disadvantage to aluminum - fatigue life. With steel, as long as you stay below a certain force amplitude, the material will last indefinitely. But with aluminum, there is no lower force limit for accumulating fatigue damage. Every time force is applied, even a miniscule one, it inches towards a fatigue failure. Generally they just design the part so that it takes an unreasonbly high number of cycles to fail, but to your point- when you have something increasing the force amplitude (such as a bad mount) that drastically increase the fatigue added to the pile with each cycle.


If you've removed the upper mounts before (especially for aftermarket bushings) - it could be the mounts insert is a bit too short. As the bolt is so large for shear strength, it's very easy to over tighten and squeeze the ears together. Since its a lock nut, just taking the slop out of it is all thats needed. Adding a washer inside (if theres a lot of slop) can help safeguard it too as it gives the ears something to squeeze down on vs just bending. Unfortunately aluminum isn't near as forgiving for that kind of stuff as steel/iron is.

Yeah, $80 is nuts - especially when there are a billion 3800 cars out there in junkyards.

Unsure, I've never seen it tried before. It is off a 60 degree v6, so the head angle is different, but its not impossible that they copy and pasted the same bolt pattern and just rotated it to work with the 60 degree casting.

3100s seem to be pretty available at junkyards - you could always pull one at the yard to compare.

 

I would be surprised if a 3100/3400 bracket would fit, but heck, I am intrigued! Curious to know.
Side note, Brandon Furches is looking for product ideas to bring to the W-body community, perhaps this is one for someone to suggest.
