...They are a little smaller and at first glance look out of place.
Interesting observation Crush. Never heard that (as far as I can remember anyway). I know they look smaller because they're taller, but I was under the impression they were patterned after the stock mounts originally. A new one at least... Not an old crushed one.
Maybe Jim can chime back in on that aspect. If anything, I would have liked to have seen them about 5/16 to 3/8" larger than original. Not for any performance reason (they've worked perfectly as is) but just the visual "beef" aspect and to fill the entire mount. But maybe some mounts have less wiggle room than others, so maybe that's not a good idea after all.
I've used re-purposed '78/'79 Bronco mounts before, to get about 3/4" of lift. They're actually too large in my opinion. Hang over the frame mounts and don't look quite right. So up to a point at least, narrower is better.
