We have a slug bulit from an ALCO S-1 or S-3.It has Blunt trucks under it currrently. We HAVE to put A.A.R. (quickly) switcher Trucks under it. long story. when we bought the slug we bought a kit for said conversion but over the years we managed to lose thie kit. All it was was an inner and outter bowl ring and side bearing clip adapaters.
Even if some one can give me the bowl dimenssions that would be a good start. I'm sure someone out there has this knowledge (Whitewater maybe?) We sure are in a bind and I'm may be able to pay for a ready made kit or trade knowledge for the same. I'm in the Locomotive busisnes so you never know when I might be able to return a favor.
thanks in advance.
