MT 100-Ton trucks will work on the Evans hoppers, but it's close. I have three of these cars, all have MT 100-T Barber trucks, ESM metal wheels, and 1015 couplers.
Two will take 18 inch radius curves with no problems. The third had to have the hopper ends scraped because the wheel flanges hit them on anything except straight track. Scrape a little plastic away and they work.
The couplers need a shim to sit at the right height. I wanted to use 0.030 inch styrene, but the axles wouldn't clear the screw, even using a flathead screw. 0.020 inch works, and is close enough to the right height. Again, two work fine, but the third (not the same one) scrapes somewhere on vertical curves. Probably the coupler screw again, but I haven't been able to find which one. It doesn't derail, and the sound isn't objectionable. Real covered hoppers frequently make odd noises as well...
A 1025 coupler would probably work better, but there's no room for the coupler box, and it may not fit even if the end is removed, as the coupler itself might be too long. I haven't tried.
For those still looking for 100-ton trucks with "standard" height bolsters, check to see if you have any of the old MDC/Roundhouse roller bearing trucks. These have a noticeably longer wheelbase than most 70-ton trucks, and a raised ring on top of the bolster. Remove the ring, add ESM (or MT plastic) 36 inch wheels, and you have 100-ton trucks that still have the standard bolster height. I don't know if it was planned, but that ring just matches the difference in height with the new wheels. On some cars, you might need to make a 0.010 inch styrene washer to go UNDER the bolster, between the truck and the head of the pin, to keep the car from rocking.
Many years ago MDC sold these trucks as parts, each piece a separate part. I bought a bunch of frames and pins, as the wheels were junk, and I cut the Rapido boxes off. I used Precision Masters plastic wheels, and body mounted couplers, saving a lot of money over MT completed trucks. Most of these ended up under 100-ton cars, because of the longer wheelbase. Once 36 inch wheels became available, it was easy to make the conversion, and most of my covered hoppers have these.
