On my 34 ford coupe frame with a 69 Lincoln 460, a Dodge omni manual rack was fitted and placed so that the ends were a straight shot at the steering arm ends. the slip joint was easily made by welding double D tubing to the shaft exiting the universal on the rack. Then a double D shaft will slip into the tubing and be overlapped by about 5". this tubing and shaft was used from a set up that had the plastic injected into the tubing to creat a collapsable shaft in case of an accident. What i did was removed the plastic so that the tubing would slide. the tubing will be filled with grease then the shaft inserted all the way in then withdrawn about 1/2"(to compensate for any suspension travel and length change. Brackets were made from 3/16 sheet with (under the main mount) a 3/8" pc cut to fit inside the bracket welded solidly to the axle to prevent any side to side flex. Then it was drilled and tapped for 3/8 bolts. Front veiw pic shows a relatively clean look with this setup and the 2" dropped stock crossmember...any additional unsprung weight will be, i beleive negligible...ps new boots and ends are on order
