I am steadily working on upgrading the driveline in my 1950 COE. Engine/Trans/Differential from the 1994 Chevy 3500HD donor truck now in place.
Next up will be the front end upgrade to disc brakes, mostly using the Grigg suggestions in the sticky at the top of the forum. IF my recipe works, I will share it.
But it is getting hard to find the steering arms for the 3500HD or P3500/P30 front axles with steering behind the axle like the COE.
