Red Caboose Hoppers

I found some old Red Caboose covered hoppers. Looking to convert to Mico Trains trucks
I think I need 1035's or 1139's ? Any help would appreciated.

Thanks
Don

 

I've used doth the 1030 roller bearing and the 1035 Barber roller bearing trucks on these. When I do that, I always reuse the manufacturer truck bolster pin on the reinstall whenever possible rather than the truck bolster pins that come with the M/T trucks.
