Who's Using Hitec Steering Servos? - Help

[Chortdakooba]

Just picked up a HS 5765MH from local hobby shop for steering in my XT. I noticed the horn post (splines) on the hitec servo is smaller than the post on the stock servo. Therefore the linkage on the truck is too big for the post on the hitec servo.
This was an out of box special, so all I got extra with it was just a round horn. What am I missing here? What all else is needed to make this servo work in this truck?

I would buy a aluminum horn for the hitec servo at davesmotors.com or largescalerc.com

I use aluminum horns on mine

I've decided to stay with the stock steering servos for now until I find they are a huge problem.
