So having missed pre-ordering these cars, I picked up a couple 3R cars that I needed to covert to 2R and Kadee couplers. I noticed the load weight which falls between 70T and 100T so I wanted to just try both Atlas trucks to see what the ride height looked like.
On the right are the Atlas 100T roller bearing trucks needing 3 Micro-Mark shims for the coupler height. On the left are the Atlas 70T trucks with no shims. Both cars I just drilled and tapped 2-56 holes for the coupler gear boxes.
One thing I noticed on the packaging of these cars, the end ladders almost fall off just looking at them. You need to be VERY careful removing these cars for the blister.
