I used 3/8" preformed transmission lines from a 1999 ram van 3500 model, I cut the ends at the front and used a 37° flare and AN-6 B nuts. I made flexible steel braded nylon coated hoses to transfer to the frame. A Derale transmission cooler thermostat valve on a home made custom bracket. A Derale transmission cooler on homemade brackets. The 3/8" hard lines have 37° AN flares and B nuts. All fittings are Russell Enduroshine fittings.
The kickdown cable is a 1995 dodge dakota V8 cable. This is attached to a homemade angle bracket on the back of the carburetor. One end of the bracket uses a part of the Dakotas throttle body kickdown mount, and part of an old mopar throttle cable mount welded on. The stud to attach the dodge Dakota kickdown cable to the carb linkage is an Edelbrock GM TH350 bolt on kickdown cable stud. Nice thing about this is with different manifold heights your linkage is unaffected
At the trans end I used a combination of kickdown lever, and return springs, and a cable attach mount. From ram van and dakota. I cant remember which pieces from which, but they fit well and have proper geometry. Wiring this all up will be the easiest part. I think the hardest part is the mechanical / physical fabrication to make it look somewhat factory. I feel I nailed it on this one.
All pix are mockups of this. I stopped work on this project about 3 years ago because of other issues. Considering starting work on it maybe this winter again. Hoping this helps with some of the other issues when fitting a 42/46RH in an A body
