For what it's worth, and this may not be a viable alternative, Pacific Limited imported two
versions of Southern Pacific gondolas in the late 1980's that differed only in the version of
the truck that was offered as under the model. Their PL-1650 represented SP Class G-50-9
gondolas with Bettendorf "T" Section trucks (and was the version that I had more interest
in as it was used under my favorite RR's version of that gon), while the PL-2000 represented
SP Class G-50-12 gondolas with what PL called an ARA 4-Spring Dalman truck, and which
may be the one that you are seeking. The engineering diagram at the top of this thread shows
7 springs in each sideframe, but it could be construed to be 4 from the way they are staggered.
Both versions of these cars show up periodically on eBay (or at shows). The usual caveat about
checking the trucks in the box, as sometimes the box may say one model, the contents may be
the other...or the trucks may be absent, or may be the AAR cast U-channel truck (Hey! Some of
the real cars were retrucked with those on the SP in the 40's and 50's, so why not the model??).
I have both versions of the PL model, but I would have to go to the storage facility to retrieve
the G-50-12 version to check the springs for the 2 different levels.
If you find a model with the correct trucks, you can demount them for use on your SAL boxcar.
And since you are going to throw the carcass of the gondola out anyway, heave it in my direction!
I have a few extra "T" Sections that I could retruck it with.
