172
im putting a PH1 gearbox onto my PH2 172 but when i had a quick look at my box tonight i noticed the gear linkage on the bottom of the box is different to my previous box! before it was a pole on the bottom of the box which inserted into the linkage pole on the bottom of the lever. now the PH1 box on the bottom is different. its more of a hole then a pole lol. do i need to get the linkage rod from a PH1 or do i upgrade my PH2???
