made my custom shift linkage....

The 1-2 rod end on the shifter side is on the wrong side of the lever, they're probably bumping into eachother. The retaining clip side of the rod ends should between the 1-2 and 3-4 levers on the shifter. The reverse rod is also on the wrong side of the shifter lever. Also the 1-2 rod looks like its going to be a little cosy with the crossmember. They do look very nice though and the heim joints should tighten up the shifts.
