That's a bad idea. Most rams have the top piece, a spacer and a wider piece on the bottom, all bolted down. Some use a few grade 8 bolts, others use 5+ soft bolts, that way if something does bind and keeps pushing, you will shear the bolts and not damage anything. It's a lot easier to replace bolts then to replace angle iron.
Here's an early pic of mine.

might be tough to see, but well there's 5 bolts.......one is out. But you can see the top piece, spacer and the bottom piece that keeps it from moving up an such. All bolts are soft bolts, found any any hardware store.
