in order to install them must you remove any fans so they fit flush on the long hood this is for gp7s and 9s? rambo1…
I think the fan needs to come out on a GP9 with 48" fans. I have a pair, but I did it so long ago I forgot. The fans are separate parts, easy to pop out if needed.
On the GP7, the fan might stay in place. The fan stays on a SD7. Should be a dimple inside the shell to drill the locating holes.
I have several Proto2000 GP7s and the hatch fits right over the fan. Just drill out the holes for the mounting pins, as marked on the inside of the shell.
