I think an FMJ clip would be and absolute nightmare on one of these cars. The track width would be petty wide, and you would have to cut everything ahead of the firewall off. At that point, you might as well do a Dakota clip and get a more modern suspension.

Old Ray,
When I moved the motor & trans back on the Dakota frame in my coupe, I bolted in a 1/4" thick plate to the frame (on each side) where the original motor mount bracket bolted to, and then drilled holes and bolted the motor mount brackets to the 1/4" plate. For the trans mount, I welded in a piece of 1/4" thick angle iron to both sides of the frame behind where the original trans crossmember bolted to the frame. I maintained the same angle the original cross member was bolted on at. Then I drilled a couple holes in each angle and bolted the trans crossmember to the angle iron. Its been working for over 40,000 miles. Gene
