First of all the Hood Needs to be modified like I did it. The grill must be changed as well. Next is the engine . The 8N has a 4 Cylinder Flathead engine. I would recommend one of the Model A engines from Revell, although it they are 1/25. I'll go for a V8 Flathead from a '50 F1 and again it is 1/25. Otherwise I'll see if TDR has a 3D printed Flatty in 1/24. The Transmission can be used because the Fergy has a 4 Speed. I you want to build a 9N or 2N you have modify it because These tractor had a 3 Speed. The Dashboard has to be modified as well. Check out Old Ford Tractors for more Information.
