I'll throw a plug in for Midwest as well. It is not just a matter of cutting some rectangular panels. The top edge is folded, there is the odd crease built in to one or two of them, and the placement of the holes and cuts are quite crucial. Then you have the welded washers on the upper holes. As well, there is the placement of some felt near the rad.
If you have a set sitting of originals right in front of you, then perhaps it's easy enough to copy. But to do it from a set of drawings over the internet might be a little problematic.
