Magnum Exhaust Manifolds in an A Body

SO HAS ANYONE MANAGED TO GET THEM TO FIT ? SO FAR I HAVE INSTALLED MANUAL STEERING,MANIFOLD SITS ON TOP OF STEERING BOX.
I DID SOME MEASURING AND CAME UP WITH SHIMMING MY ENGINE MOUNTS BY 1/2". PROBLEM SOLVED.NEXT CHALLANGE WAS CONNECTING
STEERING COLUMN TO STEERING BOX. I BOUGHT A FLAMING RIVER STEERING U-JOINT TO FIT THE MANUAL BOX 3/4"X 36 SPLINE,IT IS SO CLOSE TO FITTING BUT STILL NOT ENOUGH ROOM TO BE SAFE. TRIED MOVING THE STEERING BOX AFTER A LITTLE CUTTING AND GRINDING BUT JUST DID NOT WANT TO PRODUCE THE RESULTS I WAS LOOKING FOR.
THEN I PURCHASED ANOTHER U-JOINT FROM SPEEDWAY THAT IS SMALLER IN DIAMETER THAN THE PREVIOUS ONE AND A STEEL COUPLER 3/4"-36 SPLINE TO 3/4 ROUND 2" LONG WITH HALF BEING SPLINED:disgust:. THIS PIECE WILL MAKE YOUR SHORT COLUMN EASIER TO LENGHTEN WHEN CHANGING TO A MANUAL BOX. HAD TO WALK AWAY FROM PROJECT,TO THINK ABOUT IT SOME MORE. NOT READY TO GIVE UP YET. HOPING SOMEONE ELSE CAN GIVE SOME FEEDBACK ON THIS SUBJECT.
