One thing to remember with this kit is the pins that press into the steering arms are .75, Marlins arms and most others are 1.0, and TG’s arms are .75.
Dave from Dave'z has been running the TG kit for quite some time on his DD. He lives up by Georgetown and his shop is in Diamond Springs which is about a 30 mile trek each way on a twisty road with out any problems. It is basically the same setup as some D-44 and D-60 axles.
