Ok I finally got the body off for some clearer photos. (Quick posting/coffee break before I get the frame cleaned and primed....I only have this afternoon to do it and get it under a tent before the rain hits again)
I cleaned off some part numbers from the spring perches. The lower spring mounts are riveted. The overload spring mounts are bolted with a bracket.
