Gerabox cooler lines

[Mattrob]

Hi again. Has anyone swapped a hdd7 for a hdd6, my concern is the coolant coupler. Will the part of the coupler that screws into the housing swap over or are the threads different?

do you mean the brass union? if so then the answer is yes it should fit fine.

Thanks. Yes. The 6hdd has smaller cooler lines/coupler than the 7hdd, I'm hoping the connection with the gearcase is the same size.
