I have been building a Gullwing Mercedes replica for a number of years now.
I used this forum to guide me throughout. However when I mounted the IRS from a Thunderbird SC I mounted it as it was originally in the T-bird. As such this massively heavy unit was mounted by 4 rubber doughnuts from the 4 ends of the original K-member. Currently I am in the process of changing all this. I have acquired some Factory Five lower control arms. What I need now is some measurements frome the Factory Five support bracket. Anyone out there with a IRS unit willing to help me?
In the second picture you can see how heavy my mounting looks. The bottom picture is the Factory Five unit I need measurements from.
