Anyone install a Mangoletsi linkage for DHLA45?

[pmth95]

Anyone have experience with a Mangoletsi linkage on an Esprit?
 

To try and solve a surging idle when warm, i was going to try to install a Mangoletsi linkage

I am running into three issues (see pictures):

1) carb link bar too short by 10mm. I do have a few ideas how to extend it

2) the rear arm and pivot of the Mangoletsi interferes with both the gas hose and the choke cross carb linkage. The movement of that arm crosses both. I can re-route the gas line rather easily, but cannot think of an elegant solution for the choke link.
