I'm swapping a Quad 4 into my '87 coupe. Instead of using the front and rear engine mounts most commonly used for the Quad to Fiero swap, I'm using the mounting system from my '92 GTZ donor car. It's very similar to the way the Iron Duke was mounted in the car. I chose this route because of the parts I had on hand and because I think it makes for a much cleaner installation. One challenge is coming up with a new dog bone, since the duke's mounting point is about three inches too far to one side.
I found a photo of someone else's fabricated dog bone:
I want to make something similar, starting with an aftermarket dog bone I found at the salvage with poly bushings. I'll cut the dog bone in half, weld in a big nut and use a threaded rod to attach to the engine. While looking at my car, it occurred to me that I could just cut out the sheet metal for the stock dog bone mount and bolt or weld a new mount plate for my custom dog bone. What do you think?
I'm hesitant to cut the sheet metal, but the driver side does not have any sheet metal in the same location so it shouldn't be an issue, right?
