OK, I laid the pieces out and took a pic to clear things up (See link below). As far as measurements I took them using a reasonably good vernier caliper. Here are the measurements:

Pin diameter: .872" just under 7/8"

Closed end of the shackle hole (top): .992" just under 1"

So I'm thinking of 2 bushings 1" OD and 7/8" ID and 1 1/8" long (if I can find it) or the 1" long bushing I found. Here's the link that shows specs of that bushing:

Spring eye ID: 1.120", just under 1 1/8"

That would make the spring eye bushing 1 1/8" OD, 7/8" ID and 2" long. That's easily available as has been pointed out. Hope this helps clear things up
