kickdown linkage adjustment needed?

there is a trans go shift kit in a 904. 3rd gear is kicking in too late. I have to let off the gas a bit and it kicks in to 3rd. Which way do adjust the kickdown linkage? Its a one piece arm from the carb down to the transmission

thanks ya'll. Godspeed

Make the rod shorter.
Should be a treaded part near the carb screw it in to shorten it.
Or there will be a slider that the rod goes through at the trans if so .. loosen the 1/2" bolt and push the rod through it more.
